$$\int\limits_{0}^{1} \left(y - 1\right)\, dy$$

Integral(y - 1, (y, 0, 1))

Detail solution

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

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

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

The answer is:

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