integral of 1/((x+6)^3)

\int \frac{1}{( x + 6 ) ^{3}} d x

- \frac{1}{2 ( x + 6 ) ^{2}} + C

Solution steps

\int \frac{1}{( x + 6 ) ^{3}} d x

Apply u-substitution

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

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

Apply the Power Rule

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

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

Substitute back

u = x + 6

= - \frac{1}{2 ( x + 6 ) ^{2}}

Add a constant to the solution

= - \frac{1}{2 ( x + 6 ) ^{2}} + C

\int \frac{5}{36 - x ^{2}} d x

\int - \frac{1}{2} x^{- \frac{3}{2}} d x

\int sin (θ) - cos (θ) d θ

\int csc^{2} (x) sin (2 x) d x

\int (3 \frac{sin ( 2 x )}{sin ( x )}) d x
