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

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

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

Solution steps

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

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

Simplify

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

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

Add a constant to the solution

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

\frac{\partial}{\partial x} (e^{- (x^{2} + x y + y^{2})})

(2 x y - 3) d x + (x^{2} + 4 y) d y = 0, y (1) = 2

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

x \to + 2 lim (\frac{2 x - 25}{x - 2})

f (t) = arcsin (\frac{1}{t})
