integral of (x^4)/(sqrt(1-x^{10))}

\int \frac{x ^{4}}{1 - x ^{10}} d x

\frac{1}{5} arcsin (x^{5}) + C

Solution steps

\int \frac{x ^{4}}{1 - x ^{10}} d x

Apply u-substitution

= \int \frac{1}{5 1 - u ^{2}} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int \frac{1}{1 - u ^{2}} d u

Use the common integral:

\int \frac{1}{1 - u ^{2}} d u = arcsin (u)

= \frac{1}{5} arcsin (u)

Substitute back

u = x^{5}

= \frac{1}{5} arcsin (x^{5})

Add a constant to the solution

= \frac{1}{5} arcsin (x^{5}) + C
