The function = -38 cos(20t) (with in degrees) describes the oscillation ofa certain torsion pendulum (Figure 13-4). Assume the counterclockwise direction to be positive. Find
(a) the maximum angle to which the torsionpendulum swings;
(b) the frequency of oscillation; and
(c) the phase at which the torsion pendulum first reaches its greatest counter clockwise rotation.
