Homework Statement
[tex]\int \frac{x^{2}}{x^{2}-1}[/tex]
Homework Equations
The Attempt at a Solution
I divide bottom into the top because the degree is the same and get...
[tex]\int 1-\frac{1}{x^{2}+1}[/tex]
My question is, from here, do I have to recognize the tan[tex]^{-1}[/tex]
or is it also correct to put
x-ln [tex]\left| x^{2} + 1\right|[/tex] + c ?
