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

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
