integral of (x^2)/(sqrt(4-x^6))

\int \frac{x ^{2}}{4 - x ^{6}} d x

\frac{1}{3} arcsin (\frac{1}{2} x^{3}) + C

Solution steps

\int \frac{x ^{2}}{4 - x ^{6}} d x

Apply u-substitution

= \int \frac{1}{3 4 - 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}{4 - u ^{2}} d u

Apply Trigonometric Substitution

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

Integral of a constant:

\int a d x = a x

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

Substitute back

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

Simplify

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

Add a constant to the solution

= \frac{1}{3} arcsin (\frac{1}{2} x^{3}) + C
