Homework Statement
How can I write cos(x) in terms of cot(x)? I tried using the pythagorean identities and fundamental identities but still cannot figure it out.
The answer must start as the following: cosine(x)=...
Homework Equations
All the trig identies. I think it wants me to use the fundamental ones but I am not sure that's possible

The Attempt at a Solution
I know that cotangent=cos/sin but I need it to only be in terms of cosine which seems impossible to me because I've tried everything. Also, I do believe it is okay to use cot^2(x) with the pythagorean identities.
