\int\limits_{0}^{1} \frac{x^{2}}{x^{6} + 1}\, dx

Integral(x^2/(1 + x^6), (x, 0, 1))

Detail solution

Let $u = x^{3}$ .

Then let $du = 3 x^{2} dx$ and substitute $du$ :

$\int \frac{1}{3 u^{2} + 3}\, du$
1. The integral of $\frac{1}{u^{2} + 1}$ is $\frac{\operatorname{atan}{\left(u \right)}}{3}$ .
Now substitute $u$ back in:

$\frac{\operatorname{atan}{\left(x^{3} \right)}}{3}$
Add the constant of integration:

$\frac{\operatorname{atan}{\left(x^{3} \right)}}{3}+ \mathrm{constant}$

The answer is:

\frac{\operatorname{atan}{\left(x^{3} \right)}}{3}+ \mathrm{constant}
