(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(cos^3)(e^4(theta))

2. Relevant equations

f(x)=f(g(x))

3. The attempt at a solution

u=e^49theta))

-3sin^2(e^4(theta)) x e^4(theta)

Just not sure what I'm doing wrong, I know what the answer is I'm just not sure how to get to it.
