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

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

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

Solution steps

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

Apply u-substitution

: \int \frac{u}{2 x u ^{\frac{3}{2}} - 2} d u

= \int \frac{1}{3 u - 2} 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 - 2} d u

Apply u-substitution

: \int 2 d v

= \frac{1}{3} \cdot \int 2 d v

Integral of a constant:

\int a d x = a x

= \frac{1}{3} \cdot 2 v

Substitute back

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

Simplify

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

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

Add a constant to the solution

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

\frac{d y}{d x} = \frac{( 1 + x )}{x y ^{2}}, y (1) = 2

f (x) = \frac{x + 3}{x ^{2}}

c f (x)

x \to 0 - lim (5 + \frac{2}{x})

\frac{\partial}{\partial x} (x y^{2} + 3 x y + \frac{1}{y})
