Solving Trigonometric Equations · Exercise 186

Prove the identity.

The displacement $h (t)$ in centimeters of a mass suspended by a spring is modeled by the function $h (t) = \frac{1}{4} s in (120 π t),$ where $t$ is measured in seconds. Find the amplitude, period, and frequency of this displacement.
