Change the integral limit

  1. Mar 13, 2010 #1
    1. The problem statement, all variables and given/known data
    If I set x=cos[tex]^{2}[/tex]([tex]\theta[/tex]), the integral limit should be from 1 to 0 or need I break this integral into to 4 parts (i.e from 1 to 0 plus from 0 to 1 plus from 1 to 0 plus from 0 to 1)?

    2. Relevant equations

    3. The attempt at a solution

    Do you know any trig identities that can be used to express

    [tex]\cos(\theta) \sin(\theta)[/tex]

    in another way?
