https://math.stackexchange.com/help/on-topic mentions about what I can ask on the math site. However, I have tried asking several questions on this site. Yet, every question I asked has been closed as off-topic and deleted. This question here is almost similar to Compute $\int_0^{\pi/2}\frac{\cos{x}}{2-\sin{2x}}dx$, yet the question was closed and deleted. I have been successful in asking question on other StackExchange sites. But on the Math site, things haven't worked well. On other StackExchange sites, I still have the reputation to set bounties. Here on the Math site, I have not yet got the reputation. At https://hsm.stackexchange.com/, I am just above the reputation to set bounties, and I also have the reputation to comment. Here in the Math site, I do not have the reputation to either comment or to set bounties. I really need help asking a Math question?

    $\begingroup$ You have some pretty concrete suggestions in the comments to your post. Have you attempted to implement any of them? $\endgroup$

    $\begingroup$ You replaced the first version of the question with a different integral. This is not necessarily a bad thing, but it is odd, and produces a flashing warning sign. It almost looks like you want to dump your homework assignments here. One by one. I am not saying that's what you were doing, but you should prove that's not the case (and otherwise follow the guidelines about asking homework help) $\endgroup$ Jul 26 at 3:44

    $\begingroup$ But props for finding that other integral. What stopped you from applying the textbook method in the answer by Roman83. If you ask me, that other question is not much better. Looks like the homework solvers club upvoted it generously back in the day. Well, there were several trick solutions, which always helps. $\endgroup$ Jul 26 at 3:46

    $\begingroup$ The question about integrals that you linked here was not closed as "off-topic" but as lacking context. $\endgroup$
