If you want to treat it as a single limit (as opposed to x → x 0 and y → y 0 independently) then you need to account for all possible sequences that converge to ( x 0, y 0). The limit of f at ( x 0, y 0) only exists if the images of all such sequences converge to the same value. This is because function limits are defined in terms of ... calendar with all holidays on it

Nettet13. I am having a problem in understanding clearly what simple function actually means . Royden says: A real-valued function ϕ is called simple if it is measurable and assumes only a finite number of values. If ϕ is simple and has the α 1, α 2,..... α n values then ϕ = ∑ i = 1 n α i χ A i, where A i = {x: ϕ (x)= α i }.
