comment Compute infinite sum of a arithmetico-geometric series $\sum_{i=0}^{\infty} \frac{i}{2^i}$
I don't think you can delete a question, if there is at least one upvoted answer. But even if you could delete it, I don't think it's best thing to do.

See math.stackexchange.com/questions/92224/…, math.stackexchange.com/questions/441481/…, math.stackexchange.com/questions/87030/… and other similar questions. (Have a look at questions linked to those ones.)

comment Is there a difference between limit and "two-sided limit"?
What I consider the usual definition of limit is this one: $\forall \varepsilon > 0\ \exists \ \delta > 0 : \forall x\ (0 < |x - c | < \delta \ \Rightarrow \ |f(x) - L| < \varepsilon)$. So I suppose that your definition does not require $0<|x-c|$. (I.e., your definition requires the values being close to the limit on some neighborhood of $a$, not only in some punctured neighborhood.) IIRC both these definitions are used in literature.

comment Is there a difference between limit and "two-sided limit"?
@DanielFischer It seems that I did not read the article carefully enough. I understood that sentence as indication that it is possible that it is possible two-sided limit exists but limit at $a$ does not exist. If you make your comment into an answer, I will accept it.
