2 variable functions: graphs + limits tutorial

[@DrChrisTisdell]

@iloveyamaha1 Hi - if you're referring to Q29(f) then I've considered the case c^2 \ge 1, which covers the cases: c \le 1; c \ge 1. What you have proposed isn't quite enough to get the "whole" surface drawn.. Good question, though!

Hey Dr Chris Tisdell, you start going into "iterated limits" (31 min) and the "2 path test", but I don't believe we've covered them up to till this vid?

in the second example i.e (f) sir i think you forgot that c>=1. so while drawing the graph we have to consider the graph for x>=1 only. i hope i am right, or it would be very kind of you if you could explain if i made some mistake here. btw the vids are AWESOME....!!!
