Homework Help: Absolute Value in a double integral

  1. Dec 3, 2007 #1
    [SOLVED] Absolute Value in a double integral

    1. The problem statement, all variables and given/known data

    If [tex]\Omega[/tex] = [-1,1] x [0,2], evaluate the double integral [tex]\int\int_{\Omega} \sqrt{|y-x^{2}|} dA[/tex] given that it exists.

    2. Relevant equations

    None

    3. The attempt at a solution

    I know that in order to integrate with the absolute value I have to split the integral into two parts: When [tex]x^{2} > y ---> \sqrt{x^{2}-y} [/tex] and [tex]y > x^{2} ---> \sqrt{y-x^{2}} [/tex]

    I just can't get of the limits of the integral. Anyone have any advice on where to start or how to look at it to discover the limits? TIA
