integral of 1/((1+x)^5)

\int \frac{1}{( 1 + x ) ^{5}} d x

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

Solution steps

\int \frac{1}{( 1 + x ) ^{5}} d x

Apply u-substitution

: \int \frac{1}{u ^{5}} d u

= \int \frac{1}{u ^{5}} d u

Apply the Power Rule

: - \frac{1}{4 u ^{4}}

= - \frac{1}{4 u ^{4}}

Substitute back

u = 1 + x

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

Add a constant to the solution

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

\int \frac{sin ( \frac{1}{x} )}{3 x ^{2}} d x

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

\int 3 x^{2} - 6 - 2 e^{2 x} d x

\int (x + 2) 8 - x d x

\int \frac{y e ^{2 y}}{( 1 + 2 y ) ^{2}} d y
