Integral of 2/(x^2-1)dx HELP!
Evaluate: ∫2/(x2-1)dx
Inverse trig functions arent working.
∫1/x+1dx=ln(1+x)
My tutor and i both attemped the solution many ways, and are still at a stand still.
According to my calculator and wolfram alpha, the answer is -ln(x+1/x-1)
The closest i have gotten is 2∫[itex]1/((x+1)(x-1))[/itex]dx
