$$\int\limits_{0}^{1} \left(\frac{2}{x - 1} + \frac{1}{x}\right)\, dx$$

Integral(1/x + 2/(x - 1), (x, 0, 1))

Detail solution

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

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

$\log{\left(x \right)} + 2 \log{\left(x - 1 \right)}+ \mathrm{constant}$

The answer is:

$\log{\left(x \right)} + 2 \log{\left(x - 1 \right)}+ \mathrm{constant}$
