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

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

Detail solution

Integrate term-by-term:
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x\, dx = \frac{x^{2}}{2}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int 1\, dx = x$
The result is: $\frac{x^{2}}{2} + x$
Now simplify:

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

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

The answer is:

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