Homework Help: 2-D Delta function question

  1. Oct 28, 2007 #1
    I'm trying to plot the function f(x,y) = DiracDelta[r-r0]and then take the Fourier transform.

    Is this a radial delta function? I'm having trouble understanding the significance of this "function" .

    Try using the fact that delta function is non-zero only if its argument is zero.

    I am not sure what definition of theta you are using, but in standard radial coordinates
    tan(theta) = y/x.
