I'm trying to solve the limit of the function:
lim (x,y)→(0,0)f(x,y) =
= lim (x,y)→(0,0) 3 * x2 / (x2 + y2)
The Attempt at a Solution
x2 / (x2 + y2) is a limited function. Its image is always between 0 and 1. However I don't know what to do from here on.
What I tought was that since (x,y) → (0,0) then I can say that x = y and
x2 / (x2 + y2)
becomes 1/2. I don't think I can do this tho...
Any help or hint will be highly appreciated.
