Which trig sub do I use?

  1. Mar 1, 2012 #1
    1. The problem statement, all variables and given/known data

    [itex]\int\frac{dx}{x(x^{2}-1)^{3/2}}[/itex]

    2. Relevant equations



    3. The attempt at a solution

    I know I need to use trig sub, but which form? I can't seem to find any that fit this form.

    A triangle with x on the hypotenuse and 1 on a leg suggests ##x=\sec\theta##.
