integral of (x^2)/(-7+x^3)

\int \frac{x ^{2}}{- 7 + x ^{3}} d x

\frac{1}{3} ln - 7 + x^{3} + C

Solution steps

\int \frac{x ^{2}}{- 7 + x ^{3}} d x

Apply u-substitution

: \int \frac{1}{3 u} d u

= \int \frac{1}{3 u} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{3} ln ∣ u ∣

Substitute back

u = - 7 + x^{3}

= \frac{1}{3} ln - 7 + x^{3}

Add a constant to the solution

= \frac{1}{3} ln - 7 + x^{3} + C

\int tan^{3} (\frac{π x}{2}) sec^{2} (\frac{π x}{2}) d x

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

\int x cos (m x) d x

\int \frac{4}{( x - 7 ) ( x - 3 )} d x

\int \frac{sin ( \frac{4}{x} )}{x ^{2}} d x
