integral of (cos(x))/(sqrt((1-sin(x))))

\int \frac{cos ( x )}{( 1 - sin ( x ) )} d x

- 2 1 - sin (x) + C

Solution steps

\int \frac{cos ( x )}{1 - sin ( x )} d x

Apply u-substitution

= \int - \frac{1}{u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int \frac{1}{u} d u

Apply the Power Rule

= - 2 u^{\frac{1}{2}}

Substitute back

u = 1 - sin (x)

= - 2 (1 - sin (x))^{\frac{1}{2}}

Apply radical rule:

= - 2 1 - sin (x)

Add a constant to the solution

= - 2 1 - sin (x) + C
