Integrate sin^2

  1. Jan 29, 2009 #1
    1. The problem statement, all variables and given/known data
    For whatever reason, I'm having issues integrating sin2(x)

    2. Relevant equations
    I can use U-sub, trig-sub, integration by parts, partial fractions, in any combination as needed

    3. The attempt at a solution
    My brain is failing me, so any hints would be awesome.

    Re: Tricky Integration

    Use a double angle formula for the last one. cos(2x)=?
