A pendulum is swinging next to a wall. The distance D(t) (in cm) between the bob of the pendulum and the wall as a function of time t (in
seconds) can be modeled by a sinusoidal expression of the form a • sin(b. t) + d.
Att = 0, when the pendulum is exactly in the middle of its swing, the bob is 5 cm away from the wall. The
bob reaches the closest point to the wall, which is 3 cm from the wall, 1 second later.
Find D(t).
