@Peter I have actually voted to reopen this question. I don't find a lack of context, but I think the question itself isn't mathematical. I think it should be closed, but I don't think the reason is correct.
I mean, the electric car and so on, it looks a little nonsensical initially, but to me there is at least some information as background. How useful that information is, I don't know. I would close this question, but for being strictly non-mathematical.
@TeresaLisbon Maybe, the reason is wrong. But you seem to agree the closure nevertheless. It would be inconsequent then to reopen it just because the reason is wrong. It will be hard to close it again then.
@Peter Actually, I just forgot to notice that it hasn't been touched in 13 hours. I get the feeling this question has been abandoned. I'll place a delete vote as well.
Oh wait : no, I haven't voted to reopen this question @Peter. It was an error, it was a different question.
I just checked if I could retract the reopen vote : then I found that I didn't vote at all!
Although the duplicate target does not look like an obvious duplicate, it actually helps dispel the myth that you can manipulate this mysterious quantity called "undefined"
@Joe There are twenty two answers there! I am sure it will work out. The first answer is excellent, but I'd be extremely surprised if another answer did not work as well.
@JitendraSingh I usually practiced it this way , but everyone has to decide it for his/her own. As I am no friend of extreme richness no matter who achieved it and how , I am also not a friend of reputations passing all limits.
@Joe Always when division by $0$ is mentioned , no matter at which level, "wheel theory" is coined in. Really annoying.
@Peter: Yes, it is very annoying. I have a question: when does a question/answer become open for deletion? As far as I see, one cannot just vote to delete like you can vote to close. Does someone have to flag the question/answer for it to be deleted?
@Peter Good to know. I wonder if people consult Gradshteyn-Ryzhik for integrals. It contains not just this example but a host of other examples from every possible field. It's 1723 pages long for a reason!
Correction : 1762.
That, and a couple of other sources are UP there with anything else that integrals can offer you.
@Peter I always pick the answer which has provided the most information
But ya I asked equal information so ya your point is right @Peter but I tend to accept the answer in which answerer has more rep because as per help centre rep ≈ trust
Finally, let me please remind you all that stars in this room should be used to indicate material which people may want to refer back to in the future. Stars are not for indicating "like".
