integral of (sin(x))/((4+cos(x))^{3/2)}

\int \frac{sin ( x )}{( 4 + cos ( x ) ) ^{\frac{3}{2}}} d x

\frac{2}{( 4 + cos ( x ) ) ^{\frac{1}{2}}} + C

Solution steps

\int \frac{sin ( x )}{( 4 + cos ( x ) ) ^{\frac{3}{2}}} d x

Apply u-substitution

: \int - \frac{1}{u ^{\frac{3}{2}}} d u

= \int - \frac{1}{u ^{\frac{3}{2}}} d u

Take the constant out:

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

= - \int \frac{1}{u ^{\frac{3}{2}}} d u

Apply the Power Rule

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

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

Substitute back

u = 4 + cos (x)

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

Simplify

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

Add a constant to the solution

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

\int \frac{3}{2 x + 5} d x

\int \frac{1}{9 - e ^{2 t}} d t

\int (\frac{csc ( x )}{1 + cot ( x )})^{2} d x

\int \frac{1}{4 9 ^{2} + 9 x - 6} d x

\int \frac{4 x ^{2}}{( x - 8 ) ^{3}} d x
