Integral help

  1. Mar 7, 2010 #1

    So I'm not really sure how to go about this problem. I've attempted letting x = a few things. 4sinx, and 4tanx. Maybe trig substitution is not even the way to go. Could someone push me in the right direction?
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Yes x=2tanθ should work. Try it out and post back if you do not get through.
