The first stage of these sessions is to instill confidence in his subjects that they could visualize clear mental images containing accurate extrasensory information. This process, according to Ryzl, continued until the subject was able to perceive clairvoyantly with accuracy and detail. Finally, Ryzl attempted to wean the subject away from his own tutelage so that he or she could function independently. While still in Czechoslovakia, Ryzl claimed to have used this technique with some 500 individuals, fifty of whom supposedly achieved success. A particularly notable series of experiments were described in 1910 by EmilIe Boirac, rector of the Dijon Academy in France, which produced what he described as an "externalization of sensitivity. The most striking experiments were those in which the subject was told to project his sensibility into a glass of water. If the water was pricked, the subject would react by a visible jerk or exclamation. When the experimenter pinched the air-zone above the water-glass nearest him, or plunged his finger or pencil into it, the subject immediately reacted. Instantly the sensitive ejaculated with pain, and a small red spot appeared on the back of her hand. Boirac, as well as Soviet investigators, have reported the ability to induce a hypnotic trance simply through telepathic concentration directed toward their subjects. Of nineteen experiments reported, only seven failed to produce significant results. In a particularly interesting precognition study, conducted by Fahler and Osis with two hypnotized subjects, the task also included making confidence calls predicting which guesses would be most accurate. The correlation of confidence call hits produced impressive results with a probability of 0. Hypnosis typically involves relaxation and suggestion in an atmosphere of friendliness and trust. We do not know which of these factors, or combination of factors, accounts for heightened psi scores. Schechter himself, as well as other psi researchers, has been reluctant to conclude that hypnosis does facilitate psi performance. In a retrospective critique of research on altered states of consciousness and psi, St. Johns University psychologist Rex Stanford argued that many alternative explanations of heightened psi effects were not controlled for in the research studies. Stanford called for more rigorous process oriented research to determine why hypnosis and other altered states enhance psi scores if, in fact, they actually do. During a long period of experimental investigations, Stepanek proved to be one of the most successful subjects ever tested. In a book titled How Not To Test A Psychic, skeptic Martin Gardner reanalysed the tests with Stepanek, offering detailed hypotheses as to how the results obtained for over a decade by several independent experimental teams may have resulted from cheating by Stepanek. Martin Gardner, author of How Not To Test a Psychic, Fads and Fallacies in theName of Science, and other skeptical books (courtesy Martin Gardner) Bill Delmore In a study with an exceptional subject, Bill Delmore, confidence calls were made using a deck of ordinary playing cards as the target. The technique used was a "psychic shuffle" in which the experimenters randomly select a predetermined order which the subject must match by shuffling the target deck. In each of two shuffle series, with fifty-two cards in a series, Delmore made twenty-five confidence calls all of which were completely correct. Delmore does not seem to use an altered state of consciousness as a means of gaining psychic information. In fact, the research in altered states seems to point to other variables which are really more significant. Skeptical statistician Persi Diaconis, who observed some informal tests with Delmore which amazed a group of Harvard faculty and students, hypothesized that the results were due to a set of complicated maneuvers that would be familiar to magical practitioners. Their results, covered studies taking place over an eighteen month period: 290 In the experiments with [Uri] Geller, he was asked to reproduce 13 drawings over a week-long period while physically separated from his experimenters in a shielded room. Geller was not told who made any drawing, who selected it for him to reproduce or about its method of selection. It was never discussed by the experimenters after being drawn or brought near Geller. All but two of the experiments conducted with Geller were in the shielded room, with the drawings in adjacent rooms ranging from four meters to 475 meters from him. In other experiments, the drawings were made inside the shielded room with Geller in adjacent locations. Examples of drawings Geller was asked to reproduce included a firecracker, a cluster of grapes, a devil, a horse, the solar system, a tree and an envelope. They matched the target data to the response data with no errors, a chance probability of better than one in a million per judgment. In another experiment with Geller, he was asked to "guess" the face of a die shaken in a closed steel box. The experiment was performed ten times but Geller declined to respond two times, saying his perception was not clear. Because of the publicity which these studies received, they have been highly criticized by skeptics. To test this theory, they utilized a ganzfeld technique of covering the eyes of their subjects with halved ping pong balls so that the visual field was seen as solid white. A constant auditory environment was provided by either a white noise generator or a tape of the seashore. Under these conditions, with a constant sensory input, psi signals were expected to be easier to perceive. Subjects were put into this condition and asked to free-associate out loud while their responses were put on to magnetic tape. In another room, the telepathic sender chose, at random, a set of slides to look at and try to send to the subject. After the experiment, the subject was asked to guess which of the view-master reels, of a group of four, had been the target. The qualitative results of this procedure were often striking and statistical results also proved impressive. In 1985, a meta-analysis of 28 psi Ganzfeld studies by investigators in ten different laboratories found a combined z score of 6. Independently significant outcomes were reported by six of the ten investigators, and the overall significance 292 was not dependent on the work of any one or two investigators. Moreover, in order to account for the observed experimental results on the basis of selective reporting, it would have been necessary to assume that there were more than 400 unreported studies averaging chance results. This proportion was not appreciably lower than the proportion of published studies found significant. In evaluating the ganzfeld database, Harvard psychologists Monica Harris and Robert Rosenthal compared it in quality to research in biofeedback. An exception occurred in some ganzfeld studies when the subject was asked to choose which target picture had been "sent" by another person or agent. When slides held originally by the sender were shown to the receiver, finger smudges or other marks could theoretically have served as cues. Honorton has shown, however, that ganzfeld studies which eliminated this type of cue yielded at least as many significant psi effects as the studies with poorer controls. In response to the various criticisms which had been addressed to the ganzfeld studies, Honorton and seven associates reported on a series of eleven new experiments at the 1989 convention of the Parapsychological Association. These studies were conducted using an automated testing system which controled random target selection, target presentation, the blind-judging procedure, and data recording and storage. Targets were recorded on videotape and included both video segments (dynamic targets) and single images (static targets). The success rate for correct identification of remotely viewed targets was statistically highly significant. The likelihood that these results could have been obtained by chance was less than one in ten thousand. The results were consistent across the eleven series with eight different experimenters. The success rate for sessions using dynamic targets was significantly greater than those with static targets and accounted for most of the successful scoring. Significantly stronger performance occurred with sender/receiver pairs who were acquainted than with unacquainted sender/receiver pairs. Furthermore, comparison of the outcomes of these eleven automated ganzfeld studies with a meta-analysis of the original 28 direct hits ganzfeld studies indicated that the two sets were consistent on four dimensions: (1) overall success rate, (2) impact of dynamic and static targets, (3) effect of sender/receiver acquaintance, and (4) impact of prior ganzfeld experience. This new series of eleven ganzfeld studies provides a model for psi research in that it combined exacting methodological rigor with a consideration of the humanistic considerations essential for psi performance. Participants were all informed that they were free to bring a friend or family member to serve as their sender. Additionally, the researchers encouraged participants to reschedule their session rather than feel they must come in to "fulfill an obligation" if they were not feeling well or were experiencing personal problems. Researchers greeted participants at the door when they arrive for their session and attempted to create a friendly, informal social atmosphere. The experimenter and other staff members engaged the participant in conversation during this period. If the session involved a laboratory sender, time was taken for the sender and participant to become acquainted. The experimental protocols included many other details to help subjects feel comfortable using psi faculties. The possibility of sensory cueing was eliminated by the use of the automated target selection system. Both sender and receiver were kept in separate sound attentuated chambers during each experiment. The use of a videotape display system prevented potential cues that might result from manual handling of target pictures. Dozens of details in the experimental protocols 293 addressed every criticism which has been made of the experimental procedures. All electronic circuits, for example, were carefully monitored to exclude the possibility of even subliminal sensory leakage. All of the data from every test with every subject was reported using statistical tests which were specified in advance. The use of a large number of subjects and the significance of the outcome using subjects as the unit of analysis, rules out subject deception as a plausible explanation. The automated protocol had been examined by several dozen psi and behavioral researchers, including two well-known critics of psi research. Some participated as subjects, senders, or observers, and all expressed satisfaction with the handling of security issues and controls. In addition, two experts on the simulation of psi ability have examined the system and protocol. He is the author of more than 100 articles in mentalist periodicals, and has served as Secretary/Treasurer of the Psychic Entertainers Association. Professor Bem is well-known for the development of self-perception theory in social and personality psychology. He is also a member of the Psychic Entertainers Association and has performed for many years as a mentalist. The researchers claim that analysis has shown, contrary to the assertions of certain critics, that the ganzfeld psi effect exhibits "consistent and lawful patterns of covariation found in other areas of inquiry. The impact of target type and sender/receiver acquaintance is also consistent with trends in spontaneous case studies, linking ostensible psi experiences to emotionally-significant events and persons. Skeptic Ray Hyman and psi researcher Charles Honorton stated in a joint communique regarding the status of the ganzfeld studies:. These experiments, ideally, will be carried out in such a way as to circumvent the file-drawer problem, problems of multiple analysis, and the various defects in randomization, statistical application, and documentation pointed out by Hyman. The researchers claim they have presented a series of experiments that satisfy these guidelines. No single investigator or laboratory can satisfy the reuqirement of independent replication but the automated ganzfeld outcomes are quite consistent with the earlier psi ganzfeld studies and the psi researchers believe the burden of proof is on the critics to show why these findings should not be accepted. The automated ganzfeld studies show an overall success rate slightly in excess of 34%. A power analysis by University of California statistician Jessica Utts shows that for an effect this size, the investigator has only about one chance in three of obtaining a statistically significant result in an experiment with 50 trials. Even 294 with 100 trials, which is unusually large in ganzfeld research, the probability of a significant outcome is only about. The Experimenter Effect For some time psi researchers have been suggesting that the failure of some investigators to repIicate their findings was due to attitudes and expectations, conscious or unconscious, which were communicated through subtle sensory or psychic channels to their subjects. A number of psi research projects have been designed to study on the factors that Harris and Rosenthal identified as contributing to the experimenter expectancy effect. For half, there was a friendly, informal conversation with the experimenter for a quarter of an hour before the orientation began, and the experimenter made encouraging remarks during the breaks. The experimenter began the orientation immediately and also made discouraging remarks during the breaks. Her experimenters were six undergraduates with previous practice in conducting psychological experiments. John Beloff Beloff is a respected researcher who has consistently failed to confirm several psi experiments that have done well elsewhere. If he is a psi-inhibatory experimenter, it is not likely that his belief system is the inhibiting factor.

Long-term fear extinction sensations with the goal of reducing fear and other negative (and the success of exposure therapy) therefore hinges on reactions. Three inhibitory learning [14]; that is, the non-danger associations types of exposure can be used to help the patient face his or successfully impeding access to and retrieval of the threat her feared stimuli: situational. The degree to which threat-based versus non exposure is used for confrontation with external stimuli. As alluded to previously, abstaining from rituals classical conditioning, and that the conditioned fear response. For example, a patient response to obsessive intrusions and are intended either to might acquire a fear of toilet germs? following an anxiety reduce the likelihood of harm from the feared situation, or or disgust-provoking experience in which urine was just to reduce obsessional distress. During washing ritual to remove all of the germs when she exposure therapy, repeated confrontation with feared inevitably cannot avoid. The patient behavior might result in an immediate (and transient) confronts the fear cues and the resultant anxiety, without reduction in fear, thus negatively reinforcing these behaviors attempting to reduce it by withdrawing from the situation or (operant conditioning) leading to their becoming compulsive. One that promote fear extinction via repeated confrontation with format found to be very effective is a few hours of conditioned fear cues while resisting urges to avoid and assessment and treatment planning, followed by between perform compulsive rituals that would impede extinction twelve and twenty twice-weekly exposure sessions, lasting learning. Generally, the exposure sessions are therapy because it satisfactorily explains the maintenance of supervised by a therapist, and self-exposure practice is obsessional fear and rituals through operant conditioning. What is important is that the most distressing situations are confronted at some point during Foa and Kozak [11] proposed emotional processing treatment. According to this obsessional fear is triggered by feared situations and thoughts conceptualization, classical conditioning then occurs when, that are not objectively dangerous. Rituals are redundant the shame, disgust, or other emotions associated with these since the anxiety and fear would decrease naturally even if events become classically associated with particular body no ritual was performed. Although these safety-behaviors might temporarily engage in frequent social avoidance and other behaviors alleviate distress (and are thereby negatively reinforced), in designed to conceal, correct, check, or seek reassurance the long run they increase self-consciousness, preoccupation 280 Current Psychiatry Reviews, 2014, Vol. A enhancing an imagined defect using makeup, and wearing growing literature indicates that the prevalence of skin pants that reveal or accentuate certain parts of the body [35].

This process of scrutiny and debate oral antibiotics for acne pregnancy ciprofloxacin 250mg for sale, over many decades antibiotics for uti vomiting generic ciprofloxacin 250mg with amex, has enabled the scientific endeavor to isolate certain lines of research as deserving of serious attention bacteria klebsiella 500 mg ciprofloxacin visa. Therefore antibiotics for acne australia purchase 750mg ciprofloxacin overnight delivery, I feel comfortable including it within the realm of science rather than that of folklore virus hunter buy 1000mg ciprofloxacin free shipping. However antibiotics for uti and ear infection best buy for ciprofloxacin, before we examine the best data of psi research, let us briefly examine relevant background material in the field of psychology. The primary reasons for this is that in developing itself as a scientific discipline, psychology has moved away from the fundamental question of the human psyche in order to address more measureable, tangible issues that could properly be addressed by existing scientific methods. The concepts he used and the problems he defined have become the foundation of experimental work in sensory experience since his time. He developed the psychological measure known as the just noticeable difference (jnd) which is the smallest observable difference between two stimuli. He determined that the relationship between the intensity of a physical stimulus and the just noticeable difference at that intensity is a logarithmic one. In other words, the difference in intensity between two very bright lights will have to be much greater than the difference in intensity of two very dim lights in order for a jnd to be perceived. Unlike the psychologists who followed in his footsteps, Fechner believed he had discovered a relationship between the individual consciousness and the sublime universal soul. William James At the turn of the century, he outlined the foundations for the discipline of psychology that would include cognitive science, transpersonal psychology (the investigation of spiritual and religious experience), and psychical research. If we could say in English, "it thinks," as we say "it rains" or "it blows" we should be stating the fact most simply and with the minimum of assumption. In his classic text, Principles of Psychology, James adopted the accepted philosophy of dualism as the appropriate underpinnings of psychology. However, in one of his most brilliant works, the posthumously published Essays in Radical Empiricism, James shifted to a position of Berkeleyan idealism, which eliminated the material world and made consciousness the only reality. He argued that implicit in empiricism 265 the philosophy upon which science is based is that we know the world only as it appears in our consciousness of it as mediated by our sensory systems. Scottish philosopher David Hume, following Berkeley, carried this implication to its reductio ad absurdum, that all we know is a "flux of impressions," where they come from and where they are, we can never know. Let me then immediately explain that I mean only to deny that the word stands for an entity, but to insist most emphatically that it does stand for a function. Structuralists studied slices of consciousness that attempted to freeze a single moment or thin cross-section of the stream. They believed that, like chemists, they should search for the elements or basic building blocks of consciousness. Many psychologists in past decades behaved as if they were embarrassed by the very name psychology. They would have preferred that the discipline be called behavioral science and that they be referred to as behavioral scientists rather than as psychologists. Yet, for historical reasons, they dominated the discipline that came to be known as psychology. Watson, who introduced behaviorism in 1912, defined psychology as a natural science that studied behavior, not consciousness, by observation and experimentation. In the beginning, Watson treated consciousness as an epiphenomenon but he later states: Behaviorism claims that "consciousness" is neither a definable nor a usable concept; that it is merely another word for the "soul" of more ancient times. Many behaviorists went so far as to argue, along with positivist philosophers, that mind or consciousness did not even exist except as a concept used in popular language. From this sad perspective, the mind itself was considered a reification, a categorical error, a semantic confusion which did not, in any real scientific sense, exist. Howard Gardner, a contemporary Harvard psychologist now engaged in resurrecting cognitive science, maintained that "it is difficult to think of this [behaviorist] phase as other than primarily negative and regressive. Early studies on classical conditioning and Gestalt principles of perception were followed subsequently by two decades of behaviorism. In the 1950s information measurement took the stage to be supplanted in the 1960s by an almost frenetic endeavor to catalog memory processes, an endeavor which culminated in the new concepts of a cognitive psychology. Currently, the study of consciousness as central to the mind-brain problem has emerged from the explorations of altered and alternative states produced by drugs, meditation, and a variety of other techniques designed to promote psychological growth. The newest fad in psychology is cognitive science which defines "mind" as system containing many components including sensory perception, memory, self-image, language, etc. By and large, cognitive scientists have used the information measurement and information processing approach to the brain-mind problem. With the rise of cognitive science, consciousness is once again gaining legitimacy within psychology. But for most of the late nineteenth and twentieth century the scientific and philosophical investigation of consciousness has occurred within the tradition that started with psychical research. The findings posed by psychical research, in my opinion, remain crucial for our understanding of the limits and nature of consciousness. Psychical research has developed many new methods since the time of William James. During the past eight decades, many hundreds of research studies have been published attempting to measure the ostensible powers of the psyche under conditions of rigorous behavioral constraints. Of course, we have learned more about the reach of the psyche than was known at the turn of the century. Eighty years of experimental progress has done little to convince the skeptical scientific community that direct psychic interactions with the environment, not mediated by the sensorimotor system, have been demonstrated. Lest we judge either science or psychical research too harshly, we will do well to understand the findings of psychology regarding the many types of error and folly to which the human mind is susceptible. It can also shed much light on the dynamics of the debate between proponents and skeptics of various psychic claims. In the following excerpt from my Thinking Allowed interview with him, he states: There are many aspects of our culture that do seem to express a death instinct. One illustration is that many contemporary academic philosophers, scientists and psychologists deny the existence of consciousness. I think that we can see this process taking place on many different levels of our culture: the way we are destroying the environment, the way we use our intelligence to create weapons that threaten us with mass extinction. Pribram, "Mind, Brain and Consciousness: the Organization of Competence and Conduct," in Julian M. I would argue that, if the data of psi research has validity, it probably belongs within psychology. Rhine felt constrained to use the German term parapsychology to describe his research. Perhaps, however, the name parapsychology denotes an artificial distinction which presently creates more problems than it solves. Understanding the mechanisms by which humans repeatedly make errors of judgment has been the subject of psychological study for many decades. Why do people disagree about beliefs despite access to the same evidence, and why does evidence so rarely lead to belief change? Psychological research has examined numerous risks of assessing evidence by subjective judgment. These risks incude information-processing or cognitive biases, emotional self-protective mechanisms, and social biases. All of these factors play a major role in both sides of the debate betwen proponents and opponents of psychic phenomena. No analysis of the controversies surrounding the nature of the human spirit, and its propensity for greatness, would be complete without a realistic look at the human proclivity for folly. The Psychology of Cognitive Biases the investigation of cognitive biases in judgment has followed from the study of perceptual illusions. Our understanding of the human visual system, for example, comes in large part from the study of situations in which our eye and brain are "fooled" into seeing something that is not there. In the Muller-Lyer visual illusion, for example, the presence of opposite-facing arrowheads on two lines of the same length makes one look longer than the other. Cognitive judgments have a similar feeling of "truth" it is difficult to believe that our personal experience does not perfectly capture the objective world. With a ruler, we can check that the two lines are the same length, and we believe the formal evidence rather than that of our fallible visual system. In the 1950s, researchers began to compare how well expert judgments compared with simple statistical combining rules in predicting mental health prognoses and other personal outcomes. Typically, such studies involved providing several pieces of information such as personality and aptitude test scores about patients or job applicants to a panel of experts. These expert judges would then record their opinion about the likely outcome in each case. Statistical predictions were obtained using a "best fit" procedure that mathematically combined pieces of information, and determined a cutoff score that would separate "health" from "pathology" or job "success" from "failure. The expert judges in these studies were confident that statistical models could not capture the subtle strategies they had developed over years of personal experience. Many studies indicated "that the amount of professional training and experience of the judge does not relate to this judgmental accuracy. Ironically, the clinicians involved were typically very confident in their intuitive judgment. One of the basic errors typical to intuitive judgments is called the confirmation bias. If you hold a theory strongly and confidently, then your search for evidence will be dominated by those attention-getting events that confirm your theory. People trying to solve logical puzzles, for example, set out to prove their hypothesis by searching for confirming examples, when they would be more efficient if they would search for disconfirming examples. It seems more natural to search for examples that "fit" with the theory being tested, than to search for items that would disprove the theory. With regard to psychic phenomenon, this bias would explain why "skeptics" always seem to find reasons for doubting alleged instances of telepathy or clairvoyance, while "believers" continually find new instances to support their existing beliefs. Clinical psychologists have been shown to maintain invalid diagnostic theories based on cultural stereotypes. This occurred prcisely because the clinicians were overly impressed by "successful" pairings of a symptom and a diagnostic outcome and did not notice the many trials where the relationship did not hold. In one study, clinicians were struck by the number of trials where paranoid patients drew staring eyes, but did not consider the number of trials where non-paranoid patients drew staring eyes to be relevant. People in virtually all professions (except horse-racing handicappers and weather forecasters, who receive repeated objective feedback) are much more confident in their judgments and predictions than their performance would justify. One of the few ways to temper this overconfidence is to explicitly ask people to list the ways that might be wrong for, unless prodded, we will only consider the confirmatory evidence. A dramatic example of the confirmation bias is the problem of the "self-fulfilling prophecy. Especially well-known is the study by Harvard psychologists Rosenthal and Jacobson entitled "Pygmalion in the Classroom. Based on the expectations created by this information, the teachers went on to treat the randomly selected "late bloomers" so differently that these students scored especially highly on subsequent achievement tests. Similar situations may occur between employers and their employees, between doctors and their patients, and between psychotherapists and their clients. In other words, experimenters may obtain the predicted results because they expected their subjects to behave as they did even if the theory they were testing had little or no validity. Although originally fraught with controversy, the existence of interpersonal expectancy effects is no longer in serious doubt. In 1978, Rosenthal and Rubin reported the results of a meta-analysis of 345 studies of expectancy effects. This meta-analysis demonstrated the importance of expectancy effects within a wide variety of research domains including reaction time experiments, inkblot tests, animal learning, laboratory interviews, psychophysical judgments, learning and ability, person perception, and everyday situations or field studies. This is because the first studies on a given treatment technique are typically carried out by creators or proponents of the technique who tend to hold very positive expectations for the efficacy of the technique. It is not until later that the technique may be investigated by more impartial or skeptical researchers, who may be less prone to expectancy effects operating to favor the technique. People who try to determine if others are outgoing ask questions about extroverted qualities and discover that most people are, indeed, extroverts. People who try to determine if others are shy ask about introverted qualities and discovery that most people are introverts. Men who believe that they are having a phone conversation with an attractive woman talk in an especially friendly way. When they do this, their unseen woman partner responds in friendly and "attractive" ways. People with strong pre-existing beliefs manage to find some confirmation in all presentations. The biased assimilation of evidence relevant to our beliefs is a phenomenon that seems true of others, but difficult to perceive in ourselves. Students from the opposing schools watched a movie of the rough 1951 football game and were asked to carefully record all infractions. Yet, the students used objective trial by trial recording techniques and they still saw different infractions if they were on different sides. Social psychologists at Stanford University presented proponents and opponents of capital punishment with some papers that purported to show that deterrence worked, and other findings showing that capital punishment had no deterrence effect. They reasoned that common sense should lead to a decrease in certainty in the beliefs of both partisan groups. But if partisans accept supportive evidence at face value, critically scrutinize contradictory evidence, and construe ambiguous evidence according to their theories, both sides might actually strengthen their beliefs. Both groups believed that the methodology that had yielded evidence supportive of their view had been clearly superior, both in its relevance and freedom from artifact, to the methodology that had yielded non-supportive evidence. In fact, however, the subjects were evaluating exactly the same designs and procedures, with only the purported results varied. This result could lead to a sense of pessimism for proponents of science who think that truth may be arrived at by the objective, scientific collection of data, and by a solid, replicable base of research. Giving the same mixed evidence to two opposing groups may drive the partisans farther apart.

Make correspondence between ratios of sides of a Pythagorean triangle and the trigonometric functions of one of its angles antibiotics for acne does it work discount 1000mg ciprofloxacin with amex. Review properties of the functions sin(x) and cos(x) and other trigono metric functions virus free screensavers effective 750mg ciprofloxacin. State and apply the connections between these functions (?trigonometric identities?). Trigonometric functions are closely associated with angles and ratios of sides of a right-angle triangle. Before we articulate these connections, we must agree on a universal way of measuring angles. One is to assign a value in Radius, R degrees, with the convention that one complete revolution is represented by 360. By construction, the diameter D of a circle is a distance that corresponds to twice the radius R of that circle, so D = 2R. Mastered Material Check Now consider a circle of radius R = 1 (called a unit circle) and denote by s 1. If the radius of a circle is 2 and an In particular, for one complete revolution around the circle, the arclength is arc on its perimeter has length 0. Note that (like degrees or other measures of angles), a radian is a number that carries no units. We can now use this measure for angles to assign values to any frac tion of a revolution, and thus, to any angle. The length of an arc along the perimeter of a circle of radius R corre sponding to an angle? An angle in radians is the ratio of the arclength it subtends in a circle to the radius of that circle (and hence, a radian carries no units). Label cos(t) and sin(t) where Consider a point (x,y) moving around the rim of a circle of radius 1, and appropriate on Figure 14. The radius vector to the point (x,y) forms an angle t (radians) with, (x, y) the x-axis. The hy parameter a or shift the slider on a to potenuse in our diagram is simply the radius r = 1 of the circle. This means that the x coordinate of any point (x,y) on the unit circle cannot be larger than 1 or smaller than? Review Appendix F and then use triangles to determine the x and y coordinates of angles of 60? In this sense, the functions are twins?, and as such we expect many relationships connecting them. This is an important relation, (also called a trigonometric identity), and one that is frequently used. Turn scribed above, several others are historically important and are encountered the graphs on or off by clicking on the (grey) circles to the left of the formulae. These include the following: Notice the vertical asymptotes on some of these functions and think about sin(t) 1 where these asymptotes occur. Graphically, this means that if we shift the function by a constant distance? along the horizontal axis, we see the same picture again. Thus, as expected, the trigonometric functions are periodic, that is sin(t) = sin(t + 2? Phase, amplitude, and frequency Mastered Material Check In Appendix C we review how the appearance of any function changes when 9. The the amplitude of the graph, A scales the y axis so that the oscillation swings between a minimum of? What is the period of a between frequency and period is: trigonometric functions whose frequency is 5 cycles per min? Another common variant of the same function can be written in the form y = f (t) = Asin(? Some of the scaled, shifted, sine functions described here are shown in Figure 14. Suppose t represents time in seconds, and let y = f (t) represent the electrical activity (in mV) Figure 14. Then, since this pattern repeats, the function f is periodic, with period T = 1 second. Then this relationship no longer holds, since heartbeats become more frequent, and the length of their period, T, decreases. This suggests a more natural way to mark off time the amount of time it takes to complete a heartbeat cycle. Then the connection between clock time t and cycle time is t = time in seconds = number of cycles?length of 1 cycle in sec =? Since f is a periodic function, we can join up? its two ends and wrap it Determine T and interpret this situation. Then successive heartbeats are depicted by traversing the circle over and over again. This suggests identifying the beginning of a cycle with 0 and the end of a cycle with 2. Express the periodicity of the function f both in terms of the period T and the frequency? This relationship holds for any regular heartbeat, whether at rest or exercise where the frequency of the heartbeat,? It is sometimes convenient to represent such phenomena with a simple periodic functions, such as sine or cosine. Given some periodic process, we determine its frequency (or period), ampli tude, and phase shift. We create a trigonometric function (sine or cosine) that approximates the desired behaviour. To select a function, it helps to remember that (at t = 0) cosine starts at its peak, while sine starts at its average value of 0. In most cases, the choice of sine or cosine to represent the cyclic phenomenon is arbitrary, they are related by a simple phase shift. We then select the amplitude, and horizontal and vertical shifts to complete the process. Approximate the cyclic changes of daylight through the season using the sine function. On Sept 21 and March 21 the lengths of day and night are equal, and then there are 12 hours of daylight (each of these days is called an equinox). Suppose we identify March 21 as the beginning of a yearly day night length cycle. The period of the function we want is thus T = 365 and its frequency (in units of per day) is? We have decided to start a cycle on a day for which the number of daylight hours is the average value Mastered Material Check (12). In August, the average number of best describes the number of hours of daylight at different times of the year daylight hours is 14. Approximate the cyclic variations in this hormone level with the appropriate periodic trigonometric H(t) period: T = 24 hrs function. This means that the period of oscillation is 24 hours, so that the frequency is 50 2? T 24 12 the level of hormone varies between 0 and 100 ng/ml, which can be ex 0 t pressed as 50 50 ng/ml. From the given information, we see that the average level is 50 ng/ml, and that the origin of a sine curve should be at t = 13. In selecting the periodic function to use for this example, we could have made other choices. For example, the same periodic can be represented by any of the functions listed below:? Construct a periodic function to describe the changing phases, starting with a new moon? (totally dark) and ending one cycle later. To obtain a positive function in the desired range for P(t), we add a constant and scale the cosine as follows: 1 [1 + cos(? Given any of the trigonometric functions, identify the suitably restricted domain on which an inverse function can be de? Simplify and/or interpret the meaning of expressions involving the trigono metric and inverse trigonometric functions. Trigonometric functions provides another opportunity to illustrate the roles and properties of inverse functions. The inverse of a trigonometric function leads to exchange in the roles of the dependent and independent variables, as well as the the roles of the domain and range. However, we must take care that the resulting graph rep resents a true function, i. Why is the range of tan(x) fact that these functions repeat their values in a cyclic pattern means that a? Geometrically, this means the graphs of the trigonometric functions intersect a horizontal line in numerous places. Turn the graphs on or off by clicking on the tions to a portion of their graphs that does not repeat. This means that the functions sin(x) and arcsin(x), reverse (or invert?) each other?s? Note: the allowable values of x that can be substituted in? are not exactly Mastered Material Check the same for these two cases. We cannot use the same interval (as that for sine) to restrict the cosine function because cos(x) is an even function, symmetric about the y axis (and not one-to-one on the interval? The meaning of the expression y = arccos(x) is the angle (in radians) whose cosine is x. Unlike the case for Sin(x), we must exclude the endpoints, where the function tan(x) is unde? Again in contrast to the sine function, as x approaches either endpoint of this interval, the value of Tan(x) approaches A summary of the above inverse trigonometric functions, showing their graphs on a single page is provided in Figure F. For other values of x, one has to calculate the decimal approximation of the function using a scienti? Simplify the expression in this same triangle is the ratio of the opposite side to the adjacent side, sin(arccos(x)). The cosine of this angle is the ratio of the adjacent side to the hypotenuse, so that 1 cos(arctan(x)) = v. This chapter introduced and reviewed angles, cyclic processes, trigonomet ric, and periodic functions 2. Applications addressed in this chapter included: (a) electrocardiograms detecting the electrical activity of the heart; (b) daylight hours? If, in a 1-minute interval, a heart beats 50 times, what is the length of a heart beat cycle? Convert the following expressions in degrees to radians: (e) 100,o (f) 8,o (g) 450,o (h) 90. Find the appro priate trigonometric function to describe the following rhythmic processes: (a) Daily variations in the body temperature T(t) of an individual over a single day, with the maximum of 37. Find the appro priate trigonometric function to describe the following rhythmic processes: (a) the displacement S cm of a block on a spring from its equilibrium position, with a maximum displacement 3 cm and minimum displacement? It has a maximum displacement of 12 meters and a minimum of 8 meters, a period of 3 seconds, and an initial displacement of 11 meters when measurement was? Which of the following trigonometric functions could be used to approximate this cycle? By using a right v triangle whose sides have length 1,x and 1 + x2 we can verify that p cos(arctan(x)) = 1/ 1 + x2. The function y = tan(arctan(x)) has which of the following for its domain and range? We compute derivatives, and then use these results in a medley of problems on optimization, related rates, and differential equations. Using the quotient rule, compute derivatives of tan(x), sec(x), csc(x), and cot(x). Using properties of the inverse trigonometric functions and implicit differentiation, calculate derivatives of arcsin(x), arccos(x), and arctan(x). Limits of trigonometric functions In Chapter 3, we zoomed in on the graph of the sine function close to the origin (Figure 3. A similar analysis of the graph of the cosine function, leads to a second Mastered Material Check important limit: 1. Based on properties of the sine We can now apply these to computing derivatives of both the sine and the function, estimate the value of sin(x) for x = 0. Repeat this for estimates of cos(x) Derivatives of sine, cosine, and other trigonometric functions for these two values of x. Let y = f (x) = sin(x) be the function to differentiate, where x is now the independent variable (previously t). We can now calculate the derivative of the any of the other trigonometric functions using the quotient rule. Verify one or more of the derivatives d tan(x) sin2(x) + cos2(x) of csc(x), sec(x) or cot(x) using the =. For what ranges of values of x and y But the numerator of the above can be simpli? For what range(s) of values of y are these two functions not inverses of d tan(x) 1 2 = = sec (x). Suppose that the minimum and maximum volumes are 1400 and 3400 ml, respectively, and that the maximum rate of change of V is 1200 ml/sec.
