In the answer box below, type an exact answer only (i.e. no decimals). You do not need to fully simplify/reduce fractions and radical expressions. 12 and tan B 37 If sin a = 4, with a in quadrant IV and 3 in quadrant IV, then find tan(a -B). tan(a – B) =

Subtract 1sinsin.

Find. sin tan-1 +16 + 16 +16 a

The angle 0 made by a swinging pendulum and a vertical line is given by 0 = 0.8 cos (xt) radians, where time t is measured in seconds. What is the maximum (positive) angle made by the pendulum? (Use decimal notation. Give your answer to one decimal place.) maximum angle: radian How often does the pendulum return to this maximum ang (Give an exact answer. Use symbolic notation and fractions where needed.) pendulum returns to maximum angle: seconds
