lim (x,y)→(0,0) sqrt(x*y) / (x^2 - y^2)
Homework Equations
The Attempt at a Solution
I've tried to approach it from different coordinates (y=x, y=0, x=0, y=sqrt(x),...) but I didn't found any limit...
I also tried to prove it didn't exist with the iteration property without luck...
Any hint would be highly appreciated.
Thanks.
