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

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

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 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

\int sin (2 x y) d x

\frac{\partial}{\partial z} (x^{2} yz + \frac{1}{x y z ^{2}})

\int \frac{1}{25 x ^{2} + 2} d x

2 x y y^{^{'}} = 3 y^{2} + x^{2}

\int \frac{e ^{x}}{( e ^{x} - 4 ) ( e ^{2 x} + 1 )} d x
