Show that the limit as (x,y) -> 0 doesn't exist.
To prove it, I must use the definition of limit (the epsilon and delta thing).
Well, if the limit exists, and is 1, given any we can find a such that if
perhaps we can ty
I'm not sure how to complete this proof to conclude that doesn't exist... some help with this is very much appreciated.
