integral of (cos(x))/((1+sin(x))^2)

\int \frac{cos ( x )}{( 1 + sin ( x ) ) ^{2}} d x

- \frac{1}{1 + sin ( x )} + C

Solution steps

\int \frac{cos ( x )}{( 1 + sin ( x ) ) ^{2}} d x

Apply u-substitution

= \int \frac{1}{u ^{2}} d u

Apply the Power Rule

= - \frac{1}{u}

Substitute back

u = 1 + sin (x)

= - \frac{1}{1 + sin ( x )}

Add a constant to the solution

= - \frac{1}{1 + sin ( x )} + C
