# Use polar coordinates to find the limit

#### Faka

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?

#### Faka

what do you mean exactly?
