Homework Help: When does this double integral converge?

  1. May 6, 2007 #1
    For the double integral find which values of k make it converge.
    [tex]\int \int \frac{dA}{(x ^ 2+y^2)^k}[/tex]

    [tex] x^2 + y^2 <= 1 [/tex]
    I have no idea how to even start going about this, can just about do the basics of multiple integration but not this.

    What is z?

    Doesn't say, that is all the information I have.

    Well, is z associated with the integral? Because it really has no bearing on the problem at the moment.... perhaps you meant k?

    Yes I did, sorry!
    Will edit it now.

    Try converting it to polar coordinates

    Thanks, really didn't have a clue what to do.
