- A height of a rider on a Ferris wheel can be modeled using a sinusoidal function. The rider's height, h in meters, above ground vs time, t in seconds, can be described using the equation h = -16 cos(6t) + 18 11. a) Graph the rider's height above the ground during a 3-minute ride. b) Determine the height of the rider after 110 s.
