\int\limits_{0}^{1} \frac{1}{\sqrt[3]{x} + x}\, dx

Integral(1/(x + x^(1/3)), (x, 0, 1))

Detail solution

Let $u = \sqrt[3]{x}$ .

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

$\int \frac{3 u}{u^{2} + 1}\, du$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \frac{u}{u^{2} + 1}\, du = 3 \int \frac{u}{u^{2} + 1}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int \frac{u}{u^{2} + 1}\, du = \frac{\int \frac{2 u}{u^{2} + 1}\, du}{2}$
    1. Let $u = u^{2} + 1$ .
      
      Then let $du = 2 u du$ and substitute $\frac{du}{2}$ :
      
      $\int \frac{1}{2 u}\, du$
      1. The integral of $\frac{1}{u}$ is $\log{\left(u \right)}$ .
      Now substitute $u$ back in:
      
      $\log{\left(u^{2} + 1 \right)}$
    So, the result is: $\frac{\log{\left(u^{2} + 1 \right)}}{2}$
  So, the result is: $\frac{3 \log{\left(u^{2} + 1 \right)}}{2}$
Now substitute $u$ back in:

$\frac{3 \log{\left(x^{\frac{2}{3}} + 1 \right)}}{2}$
Add the constant of integration:

$\frac{3 \log{\left(x^{\frac{2}{3}} + 1 \right)}}{2}+ \mathrm{constant}$

The answer is:

\frac{3 \log{\left(x^{\frac{2}{3}} + 1 \right)}}{2}+ \mathrm{constant}
