Modeling with Trigonometric Functions · Exercise 32

Construct an equation that models the described behavior.

The displacement $h\left(t\right),$ in centimeters, of a mass suspended by a spring is modeled by the function $h\left(t\right)=-5cos\left(60\pi t\right),$ where $t$ is measured in seconds. Find the amplitude, period, and frequency of this displacement.

Its source prints no answer for this problem, so there's nothing to check against.
