 * Student Answers || Student Feedback || Teacher Feedback ||
 * 57. False. It is only true for -1 is less than or equal to x, which is less than or equal to 1 ||  || False for lower case sine inverse.
 * 58. False. It only has one horizontal asymptote at x=0 ||  || arctan means the same as tangent inverse.
 * 59. E. -sq root 3/2 is the x coord. for 150 deg., which is 5 pi/6 ||  || correct ||
 * 60. C. pi radian is equal to 180 deg., so the sine of pi is 0, and the sine inverse of 0 is 0 deg. ||  || correct ||
 * 61. C ||  || Answer is C ... sorry I assigned this one. We will look at this material after the midterm break. ||
 * 62. A. The graph of arcsin(x) is continuous vertically. ||  || answer is A for lower case inverse, E for capital inverse. ||
