5) (10 pts) For = arctan(3/2), find the exact values of (a) sin(), (b) cos(), (c) csc(), and (d) cot().

6) (10 pts) Let d/dt=5deg/sec when = 50 deg and and h are related by tan() = h/40. Find dh/dt . h is in feet. t is in sec. Convert degrees to radians as the first step to doing the problem. Include units in your answer.
