integral of (x^2)/(sqrt(1-x^3))

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

- \frac{2}{3} 1 - x^{3} + C

Solution steps

\int \frac{x ^{2}}{1 - 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

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= - \frac{1}{3} \cdot 2 u^{\frac{1}{2}}

Substitute back

u = 1 - x^{3}

= - \frac{1}{3} \cdot 2 (1 - x^{3})^{\frac{1}{2}}

Simplify

- \frac{1}{3} \cdot 2 (1 - x^{3})^{\frac{1}{2}} : - \frac{2}{3} 1 - x^{3}

= - \frac{2}{3} 1 - x^{3}

Add a constant to the solution

= - \frac{2}{3} 1 - x^{3} + C

\int \frac{2}{x ^{2} + 16} d x

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

\int \frac{9}{x 4 - 81 ln ^{2} ( x )} d x

\int 50 - \frac{x}{2} d x

\frac{d x}{d y} = - \frac{x}{y}
