Homework Equations
Need to integrate x^2/((x^2-1)^(1/2)).
The Attempt at a Solution
I first broke the equation into (x^2-1)^(1/2) + (x^2-1)^(-1/2)
Hence Integral (x^2/((x^2-1)^(1/2))) = Integral((x^2-1)^(1/2)) + Integral((x^2-1)^(-1/2)))
Further on Integral((x^2-1)^(1/2)) is an integral by parts.
Hence Integral((x^2-1)^(1/2)) = x(x^2-1)^(1/2) - Integral(x^2/((x^2-1)^(1/2)))
Therefore Integral (x^2/((x^2-1)^(1/2))) = 1/2(x(x^2-1)^(1/2) + Integral((x^2-1)^(-1/2))
But now I am stuck on how to solve the Integral((x^2-1)^(-1/2)).
I am sorry that I can't put this into Latex form as my name suggest I don't know how to use Latex.
