comment Why is 'abuse of notation' tolerated?
@Korgan I have been in the same boat as you are and have tried to use completely correct and well-defined notation as long as possible. Believe me, in a course as simple as basic analysis, I was not able to proceed much further than 6-7 sections without having to write stuff too much tediously. I instead gave up and adopted the loose notations.

@TMM By as cool as an ice, I meant, I am quite resistant to personal insults and less likely to be depressed by the site. I share a good camaraderie with quite a lot of members on chat. I have till now being more of an active participant in chat rather than main. If/when I am elected a moderator, I will of course extend my focus to main. :-)

comment Factoring a long expression in the form $(a+b)^3 + (c - b)^3 - (c+b)^3$
@pen you have $(c-b)^3 - (c+a)^3$.

@PeterTamaroff Try that without the double negative.

revised Compute using Complex Analysis: integral
Asking a question and then changing it is as much a act of vandalism as is deleting the question text.

comment Given a generating function for $\sum a_n z^n$, what is the generating function of $\sum a_n^2 z^n$
There seems to be something off in your title.

comment A really complicated calculus book
@Thomas Mention those books in your question, that will give people a better idea on how to answer.
