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)=.....

2. Relevant equations

All the trig identies. I think it wants me to use the fundamental ones but Im not sure thats possible

3. 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.
