    Unable to find a suitable substitution to integrate a function.

    Hi,

    I have the following function, but I really cannot find a substitution that helps me integrate it :-/. I'd really appreciate it if anyone could give me a clue on a suitable substitution. Thanks!

    (x^2)/(x^2-1)^(1/2)
