integral of 1/((2x+1)^5)

\int \frac{1}{( 2 x + 1 ) ^{5}} d x

- \frac{1}{8 ( 2 x + 1 ) ^{4}} + C

Solution steps

\int \frac{1}{( 2 x + 1 ) ^{5}} d x

Apply u-substitution

: \int \frac{1}{2 u ^{5}} d u

= \int \frac{1}{2 u ^{5}} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u ^{5}} d u

Apply the Power Rule

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

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

Substitute back

u = 2 x + 1

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

Simplify

\frac{1}{2} (- \frac{1}{4 ( 2 x + 1 ) ^{4}}) : - \frac{1}{8 ( 2 x + 1 ) ^{4}}

= - \frac{1}{8 ( 2 x + 1 ) ^{4}}

Add a constant to the solution

= - \frac{1}{8 ( 2 x + 1 ) ^{4}} + C

\int csc (5 x) cot (5 x) d x

\int_{2}^{5} \frac{5}{x - 2} d x

\frac{d}{d y} (2 x (y))

\frac{d}{d x} (\frac{( - x ^{2} - 5 )}{( x ^{2} - 5 ) ^{2}})

- 2 e^{3 t}
