Need help with this integration

  1. Oct 30, 2009 #1
    1. The problem statement, all variables and given/known data
    S dx/(1-x^2)^(3/2)


    2. Relevant equations



    3. The attempt at a solution

    I tried seperating the bottom

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

    then tried to use integration by parts.... but I think that doesn't work..

    how would I get the power to 1/2?

    thank you in advance

    Hi kira137! :smile:

    (have a square-root: √ and try using the X2 tag just above the Reply box :wink:)

    Alternative hint: can you integrate x2/(1 - x2)3/2 by parts ? :wink:
