integral of (sin(x))/(sqrt(4-cos(x)))

\int \frac{sin ( x )}{4 - cos ( x )} d x

2 4 - cos (x) + C

Solution steps

\int \frac{sin ( x )}{4 - cos ( x )} d x

Apply u-substitution

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

Apply the Power Rule

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

Substitute back

u = 4 - cos (x)

= 2 (4 - cos (x))^{\frac{1}{2}}

Apply radical rule:

= 2 4 - cos (x)

Add a constant to the solution

= 2 4 - cos (x) + C
