Use polar coordinates to find the limit

  1. Sep 8, 2011 #1
    Hi!
    Is there somebody, who can help me with this exercise:
    "Use polar coordinates to find the limit. [If (r, θ ) are polar coordinates of the point (x,y) with r ≥ 0, note that r --> 0+ as (x,y) --> (0,0)]

    I've done this so far. I do not know how to determine what the limit is.

    Looks like a continuous function of r to be, what are the limits of continuous functions?
