integral of (x^4)/(6-x^5)

\int \frac{x ^{4}}{6 - x ^{5}} d x

- \frac{1}{5} ln 6 - x^{5} + C

Solution steps

\int \frac{x ^{4}}{6 - x ^{5}} d x

Apply u-substitution

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

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

Take the constant out:

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

= - \frac{1}{5} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= - \frac{1}{5} ln ∣ u ∣

Substitute back

u = 6 - x^{5}

= - \frac{1}{5} ln 6 - x^{5}

Add a constant to the solution

= - \frac{1}{5} ln 6 - x^{5} + C

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

\int \frac{1}{x ( 49 + ln ^{2} ( x ) )} d x

\int (3 + 3 tan^{2} (θ)) d θ

\int e^{- x} + e^{x} d x

\int \frac{ln ^{4} ( x )}{x ( ln ^{2} ( x ) + 1 )} d x
