$\frac{\sin\left(x\right)^{5}}{5}+C_0$

## Step-by-step explanation

Problem to solve:

$\int\left(sin^4xcosx\right)dx$
1

Solve the integral $\int\sin\left(x\right)^4\cos\left(x\right)dx$ applying u-substitution. Let $u$ and $du$ be

$\begin{matrix}u=\sin\left(x\right) \\ du=\cos\left(x\right)dx\end{matrix}$
2

Isolate $dx$ in the previous equation

$\frac{du}{\cos\left(x\right)}=dx$

$\frac{\sin\left(x\right)^{5}}{5}+C_0$
$\int\left(sin^4xcosx\right)dx$
