I came across this question [edit - now deleted] and looking at the number of years and his reputation at MSE I feel that the questioner has quite a good experience of how MSE works. The moment I read the question I felt it was a homework question (no matter how you phrase it) saying "Solve these integrals for me".
The question itself is a trivial high-school problem but that's not the point. My problem is with the questioner who mentioned :
I tried few trigonometric identities without good success
And that's it. No attempts or thoughts mentioned. Ideally if this was posted by a new user it would have been closed as off-topic for not showing attempts and asking homework questions (which is why I feel MSE is a top-notch Q&A site with good standards and awesome people), so, why no-one asked the questioner to show his/her work? Why did everybody start answering it even though it was a homework question?
The policies should be applicable for everyone (irrespective of experience or reputation) here, right? So why can I feel (please forgive me for that) that it's alright for experienced people to ignore the policies?
I don't want to be offensive to anyone (if it's really that much offensive, in the worst case I would delete this question) but I just want to understand why these rules are taken lightly for some people while being aggressively imposed on others?
I really respect every member here at MSE so I feel that such a silly thing should not be repeated as I have seen this behavior for quite a few questions.
A note to the people who feel like down-voting or are actually down-voting this meta question: I request you to mention the reason as well so that I can understand what is that you feel is wrong about this post. This is very important for a newbie like me to understand how things work here (because I have been here for just around two months).
