# Homework Help: Trigonometry

A carnival Ferris wheel with a radius of 7 m makes one complete revolution every 16 seconds. The bottom of the wheel is 1.5 m above the ground. The ride starts at the bottom. Find the sinusoidal function that models this Ferris wheel in terms of time (t) in seconds.

I would use this function:

h=1.5+ D*sin(wt) where D is the diamter, w = 2PI/period
