A steamroller has spot of paint on its roller. As the steamroller moves, the spot rotates around the axle. The roller has radius 1 meter and completes one full revolution every 2 seconds.

1). Construct a cosine model to describe the height of the paint spot over time.

2). Use your model to predict the height of the spot after 3.6 seconds.
