Homework Statement
Do the following limits exist? State any relevant ideas.
a) limit as (x,y) -> (0,0) of (xy)/(x2 - y2)
b) limit as (x,y) -> (0,0) of (x2)/(3x4 + y2)
c) limit as (x,y) -> (0,0) of sin(2x)/y
The Attempt at a Solution
I don't really know where to start; I can't simplify them algebraically, how else can I determine the limit?
