Solution Summary: The author explains how to solve the equation y=1-2mathrmcos2x2, then describe the graph using another equation.
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.
