$$\int\limits_{0}^{1} \left(2 - y\right)\, dy$$

Integral(2 - y, (y, 0, 1))

Detail solution

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

$\frac{y \left(4 - y\right)}{2}$
Add the constant of integration:

$\frac{y \left(4 - y\right)}{2}+ \mathrm{constant}$

The answer is:

$\frac{y \left(4 - y\right)}{2}+ \mathrm{constant}$
