[tex]\int[/tex][tex]\frac{4}{x^2-1}[/tex]

2. Relevant equations

3. The attempt at a solution

I thought I had this right...

[tex]\frac{4}{x^2-1}[/tex] = 2 ([tex]\frac{1}{x-1}[/tex]-[tex]\frac{1}{x+1}[/tex])

therefore,

[tex]\int[/tex][tex]\frac{4}{x^2-1}[/tex]=2(ln(x-1)-ln(x+1))

I then have to evaluate from 2 to 3 and I get .814, but it isn't right.
