An old man in the sea.In my study on the concept of limit, I've come across two different definitions: Let's assume that $a \in \bar D$, i.e. $a$ belongs to the closure of the domain of function $f$. Then $\lim_{x\rightarrow a}f(x)=b$ $\forall_{\epsilon>0}\exists_{\delta>0}\forall_{x}\ \ x\in D \land|x-a|<\delt...

@Anoldmaninthesea. Hi, I think that you might have a better chance to find somebody who'll have the knowledge and the time to answer you if you post in the main chat room or in Calculus and Analysis chat room.
In any case, I have at least added comment linking to similar question.
And I have also upvoted it. It deserves +1 already because it is interesting question, but even more after you have provided at least one reference to the less usual definition of limit. (Adding more references would probably be even better, but I guess they are not that easy to find.)

Sorry, I am probably not really your kind of guy. (I have never taught introductory calculus.)
But judging from the number of views and comments, your question on the main received some attention.
