People who believe in biorhythms claim that there three cycles that rule our behavior- the physical, emotional, and mental. each is a sine function of a certain period. the function for our emotional fluctuations is: e=sin pi over 14 (x) where x is measured in days starting at birth. emotional fluctuations, e are measured from -1 to 1, inclusive, with 1 representing peak emotional well-being, -1 representing the low for emotional well-being 0 representing feeling neither emotionally high nor low. a. sketch a graph of this function. b. find e corresponding to x=7,14,21, and 35. c. describe what you observe d. what is the period of the emotional cycle
