8.3 Modeling w/Trig Functions Bonus

This graph models the height of Jesse's yo-yo over time by using a trigonometric function. He starts timing the yo-yo when it is at its lowest position of 5 inches above the ground. The string length is 30 inches and it took 2.5 seconds to return to the same position.

Explain why the graph has a peak at 35 inches.
