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

Integral(1/(sqrt(1 - x)), (x, 0, 1))

Detail solution

Let $u = \sqrt{1 - x}$ .

Then let $du = - \frac{dx}{2 \sqrt{1 - x}}$ and substitute $- 2 du$ :

$\int \left(-2\right)\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\text{False}$
  1. The integral of a constant is the constant times the variable of integration:
    
    $\int 1\, du = u$
  So, the result is: $- 2 u$
Now substitute $u$ back in:

$- 2 \sqrt{1 - x}$
Add the constant of integration:

$- 2 \sqrt{1 - x}+ \mathrm{constant}$

The answer is:

$- 2 \sqrt{1 - x}+ \mathrm{constant}$
