 * Student Answers
 * 61.True: Cos(theta)>0 when theta </= 90 . Cos(theta) /= 90. ||  || correct ||
 * 62.True: The the sin value is -.6 because the point is in the fourth quadrant and the
 * 63.E: sin(-theta) + csc(theta) = -.4+1/.4 = -.4+2.5 = 2.1 ||  || correct ||
 * 64.B: When you add pi (180 degrees) to any angle measure, the x-coordinate
 * 65.A: If you square the cosine and sine values and add them together, they
 * 66.A: We know that the numerator must be greater than zero to allow the tangent
