**NOT**exist. I know that the denominator cancels out, however my lecturer says the limit does not exist because we cannot find a circle with radius [itex]\delta[/itex] that contains the point (0,0), as the function is not defined for all y=x. Here is a little drawing of the domain.

Is my lecturer's explanation valid?Thanks in advance,

Michael
