Thread: Trigonometric Differentiation Problem.

1. Trigonometric Differentiation Problem.

Hi, for the life of me I cannot figure this one out.

Find the derivative of $\displaystyle sin^4 \sqrt{u}$.

This is what I tried to do:
$\displaystyle sin^4 \sqrt{u} = (sin\sqrt{u})^4$

Thank you Plato. The answers appeared completely different to me, and in the future I will try to use the correct notation.
