Integral involving a square root which I can't work out!

  1. Apr 30, 2009 #1
    1. The problem statement, all variables and given/known data

    Hi, I'm stuck on the following integral.

    ∫ y / (√(a(y^2)-c)) dy

    where a and c are constants

    2. Relevant equations

    3. The attempt at a solution

    I've tried using standard integrals involving square roots in the denominator, but I'm unsure what to do with the y on the numerator.

    Any help would be appreciated!
