Thanks, but I finally managed to solve it.

I went with P(k-1) and P(k) instead of P(k) and P(k+1) so I wouldn't have to deal with cos(k+1)θ.

Definitely an excellent variation on proofs by induction. You'll just have to be careful with naming.... because the k=1 case becomes P(0) and P(1) instead of P(1) and P(2) like before.
