limit problem from past exam. :(
Problem from an exam that I just did is really bugging me.
lim(x,y)->(0,0) (x*y2)/(x2+y4)
The attempt at a solution[/b]
At first I thought the limit didn't exist. I tried using paths, x=y1/2, but then I couldn't find a counter example for which a path approached at a different point. So then I tried using the squeeze theorem, and got that the limit is 0. :\
Was my approach to the problem correct? is the limit really 0? [
