How do you find #int (x+1)/(x(x^2-1)) dx# using partial fractions?
You try to split the rational function into a sum that will be really easy to integrate.
First of all :
Partial fraction decomposition allows you to do that :
In order to find them, you have to multiply both sides by one of the polynomials at the left of the equality. I show one example to you, the other coefficient is to be found the same way.

You do the same thing in order to find
