The boundaries of doule integrals in polar form

  1. Mar 24, 2009 #1
    Hi I need to use a double integral to find the area of the region bounded by:

    r = 3 + 3sinQ where Q = theta.

    I know the bounds of the inner integral are from 0 to 3 + 3sinQ.

    However, I do not know how to determine the bounds of the outer integral.

    Any help would be greatly appreciated.

    Ok this seems to be a cardioid. What you found were the boundaries of r. So Where is the problem of finding theta? Just graph it. If all else fails plug in some values of theta.
