## Homework Statement

A bicycle wheel has radius R. Let P be a point on the spoke of a wheel at a distance d from the center of the wheel. The wheel begins to roll to the right along the the x-axis. The curve traced out by P is given by the following parametric equations:

x=15(θ)-6sin(θ)

y=15-6cos(θ)

## Homework Equations

When it goes cw θ< 0

## The Attempt at a Solution

I really don't know where to start, the wheel makes a cycloid shape but I don't know how to start solving for it, this question just seems so odd to me, a hint in the right direction would be appreciated?
