This is my question that get 5 downvote

Integrate $f(x) = \int \frac{\mathrm dx}{x*\ln(x)*\ln(\ln(x))*\ln(\ln(\ln(x)))*...*\overbrace{\ln(...\ln(x)...)}^{100\ \text{copies of}\ln}}$

This is another question that also get 5 downvote

Please answer all questions

But this is pretty similar question that get 4 upvote.

Integrating $\int \frac{81x-162}{x^4 + 81x^2} dx$ by parts

How to integrate $\int \frac{1}{\sin^4(x)\cos^4(x)}\,\mathrm dx$?

This one even get 9 upvote

Evaluate: $\int{\frac{x^{5}-x}{x^{8}+1}}\:\mathrm dx.$

This one get 8 upvote

evaluation of $\int\tan^{8}{x}dx$

This one even get 5 upvote

evaluation of $\int\sqrt{\frac{e^{nx}}{e^{nx}+1}}dx:n\in \mathbb{Z^*}$

This one get no upvote but no downvote

Understanding : $\int \frac{1}{x^{-1}+1}dx$

Why do those question get so many upvote but mine get so many downvote ? What are different between them ? My question and their question is very similar. Why do they get so different result ?

    $\begingroup$ In your second question, math.stackexchange.com/questions/4524506/…, you just dropped the question on ask and expected us to solve it which is not the correct manner in which to ask questions on this site. In the first, math.stackexchange.com/questions/4524322/…, your efforts are extremely vague, i.e. “substituted y=something of x” is basically no progress. What is the “something” you refer to? $\endgroup$ Sep 4 at 6:17

    $\begingroup$ @insipidintegrator The second question isn't mine. It is asked in pretty same time of mine and seem to get same result. $\endgroup$

    $\begingroup$ The other 3 questions you mention, each have included a concrete attempt by the asker. Any reader of the post can reasonably understand the OP’s approach and thought process towards solving the question. Basically, they are showing us their attempt and the specific point where they got stuck. They are asking for help at a specific step, not just asking us to solve the problem for them. $\endgroup$ Sep 4 at 6:40
  • $\begingroup$ @insipidintegrator About the first question, I have a problem to find y=something of x. "something of x" mean some form of function of x for example, y=ln(x). I have no idea what the substitute y should be. $\endgroup$

    $\begingroup$ So what do you think will happen if we try to substitute y=ln x? I suggest you proceed with the integral after substituting y=ln x and then tell us what you found. Maybe edit it into your original question as well. $\endgroup$ Sep 4 at 6:48
  • $\begingroup$ @insipidintegrator Ok, I will try on the next one if I have. But should I delete that question. It already get too many downvote and doesn't seem to be able to get back. $\endgroup$

    $\begingroup$ I wouldn’t, if I were you. Since you are new to the site, you may not know that editing a post bumps the post up to near the top of the “Interesting” posts list and to the top of the “Active” Posts list. So a few users may see your edited post, notice the edit you made, may appreciate the effort, and provide a constructive answer (and even may upvote it!) if you edit your post to show your efforts. $\endgroup$ Sep 4 at 7:02
  • $\begingroup$ @insipidintegrator Ok, I try to improve it as you suggest but it seem to still keep getting more downvote. $\endgroup$

  • $\begingroup$ Hi, I have reversed my downvote to an upvote. Also note that you have got an answer, which deals with two iterations of log instead of a 100. Can you study the top answer and try to extend it to the original question? $\endgroup$ Sep 4 at 8:09

    $\begingroup$ Also, your comments are concerning. You say you got this from a friend. Are you trying to solve this only so that you can get applause and praise from random strangers on the internet? People may have different reasons for downvoting. Maybe they’ve already seen your question somewhere else. Maybe they just don’t like looking at so many logarithms. Maybe they are in a bad mood and are on a downvoting spree and your question just got caught up in it. Basically, what I wanna say is, don’t get discouraged by downvotes. $\endgroup$ Sep 4 at 8:14

  • $\begingroup$ @insipidintegrator I don't want to get applause or praise but I don't expect to get that many downvotes. I make me feel like this site doesn't welcome. Anyway, thank you for make me feel better. $\endgroup$

    $\begingroup$ I agree, the site is slightly esoteric in nature, you have to get accustomed to its (sometimes very rigidly enforced) asking guidelines. I had benefited from answers on the site for a few years before joining, so I think I got used to it a bit more easily. By the way, you’re welcome and I hope you feel a bit more comfortable on this site. (P.S. Your question has received a few upvotes now :) and is on the verge of being reopened) $\endgroup$ Sep 6 at 11:05
  • $\begingroup$ @insipidintegrator Yes, it get some upvote and is reopened now. Thank you very much for helping me. $\endgroup$
