In a study of how monkey's eyes pursue a moving object, an image was moved sinusoidally through a monkey's field of vision with an amplitude of 9 and a period of 0:550 second. a. Find an equation giving the position of the image in degrees as a function of time in seconds. b. After how many seconds does the image reach its maximum amplitude? c. What is the position of the object after 8 seconds? a. An equation giving the position y as a function of time t is (Type an exact answer, using x as needed.)
