$$\int\limits_{0}^{1} \sqrt{x + 1}\, dx$$

Integral(sqrt(x + 1), (x, 0, 1))

Detail solution

Let $u = x + 1$ .

Then let $du = dx$ and substitute $du$ :

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

$\frac{2 \left(x + 1\right)^{\frac{3}{2}}}{3}$
Now simplify:

$\frac{2 \left(x + 1\right)^{\frac{3}{2}}}{3}$
Add the constant of integration:

$\frac{2 \left(x + 1\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}$

The answer is:

$\frac{2 \left(x + 1\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}$
