Integration of sin/cos (non-linear functions)

## Interactive practice questions

Consider the function $y=\sin\left(x^5\right)$y=sin(x5).

a

Find the derivative $\frac{dy}{dx}$dydx.

b

Hence find the value of $\int x^4\cos\left(x^5\right)dx$x4cos(x5)dx.

You may use $C$C to represent the constant of integration.
