What is the integral of 1/((2x-5)^7) ?

The integral of 1/((2x-5)^7) is -1/(12(2x-5)^6)+C

integral of 1/((2x-5)^7)

\int \frac{1}{( 2 x - 5 ) ^{7}} d x

- \frac{1}{12 ( 2 x - 5 ) ^{6}} + C

Solution steps

\int \frac{1}{( 2 x - 5 ) ^{7}} d x

Apply u-substitution

= \int \frac{1}{2 u ^{7}} 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 ^{7}} d u

Apply the Power Rule

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

Substitute back

u = 2 x - 5

= \frac{1}{2} (- \frac{1}{6 ( 2 x - 5 ) ^{6}})

Simplify

\frac{1}{2} (- \frac{1}{6 ( 2 x - 5 ) ^{6}}) : - \frac{1}{12 ( 2 x - 5 ) ^{6}}

= - \frac{1}{12 ( 2 x - 5 ) ^{6}}

Add a constant to the solution

= - \frac{1}{12 ( 2 x - 5 ) ^{6}} + C

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

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

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

\int (x^{2} + 4) cos (5 x) d x

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