Unsure if this is the correct thread but I need assistance completing this: ðĨ(ðĄ) = ð (1 â cos(ðĄ â ð)) where r = radius ð = phase shift 1 revolution = 6.28 sec

You are trying to compute the Fourier series of this? What have you tried? I suggest trying to 1st compute something easier such as the Fourier series for $f(t) = \cos(t  \Psi)$ and $g(t) = r$ separately. If you can't get these you should explain where you are getting stuck.
