Double Polar integral

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

    Convert to polar integral and integrate.

    [tex]\int_{D}\int xy dA[/tex]

    where D is the disk with the center origin and radius 3.

    I am not sure about the limits. I know that x = rcos([tex]\theta[/tex]), y = rsin([tex]\theta[/tex]), dA = rdr*d[tex]\theta[/tex]
