Question

Solve the following equation : $\frac{d}{dx}\cos \left(x^7\right)x{\sin }^2\left(x^5\right)$

Answer 1

$\frac{d}{dx}\cos \left(x^7\right)x{\sin }^2\left(x^5\right)=-7x^6\sin \left(x^7\right)x{\sin }^2\left(x^5\right)+\cos \left(x^7\right){\sin }^2\left(x^5\right)+\cos \left(x^7\right)x.\sin \left(2x^5\right).5x^4$
