integral of (6x^5)/((x^6-1)^2)

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

- \frac{1}{x ^{6} - 1} + C

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int \frac{1}{6 u ^{2}} d u

= 6 \cdot \int \frac{1}{6 u ^{2}} d u

Take the constant out:

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

= 6 \cdot \frac{1}{6} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= 6 \cdot \frac{1}{6} (- \frac{1}{u})

Substitute back

u = x^{6} - 1

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

Simplify

6 \cdot \frac{1}{6} (- \frac{1}{x ^{6} - 1}) : - \frac{1}{x ^{6} - 1}

= - \frac{1}{x ^{6} - 1}

Add a constant to the solution

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

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

\int \frac{3 - e ^{x}}{e ^{7 x}} d x

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

\int 9 - 16 y^{2} d y

\int \frac{4 x ^{3} - 8 x ^{2} + 9}{x ^{2} - 2 x} d x
