$$\int\limits_{0}^{1} \sin{\left(x \right)} \sin{\left(x \right)} \cos{\left(x \right)}\, dx$$

Integral((sin(x)*sin(x))*cos(x), (x, 0, 1))

Detail solution

Let $u = \sin{\left(x \right)}$ .

Then let $du = \cos{\left(x \right)} dx$ and substitute $du$ :

$\int u^{2}\, du$
1. The integral of $u^{n}$ is $\frac{u^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int u^{2}\, du = \frac{u^{3}}{3}$
Now substitute $u$ back in:

$\frac{\sin^{3}{\left(x \right)}}{3}$
Add the constant of integration:

$\frac{\sin^{3}{\left(x \right)}}{3}+ \mathrm{constant}$

The answer is:

$\frac{\sin^{3}{\left(x \right)}}{3}+ \mathrm{constant}$
