At times, my learning parters at the university have a hard time solving certain problems.

Is it legitimate to post a self answered question, to help them, and at the same time, help others with an example?

*I found no other convenient communication method which I can write math in.

    $\begingroup$ If the main goal is to help those you are studying with, I would say no. If you feel that the question and answer will be useful for a wider audience, then it should be fine (note that if it is some very specific exercise, most people will probably find it too localized to be useful). For communicating with those you study with, there are plenty of better options. $\endgroup$ Sep 9, 2013 at 10:36
  • $\begingroup$ @TobiasKildetoft What options could you suggest? Because writing math in Skype is painful. $\endgroup$

    $\begingroup$ For long things, make it a .pdf and send it to them. For shorter things, make your own chatroom here and use the bookmarklet to enable MathJax, or write things on mathbin.net. $\endgroup$ Sep 9, 2013 at 10:43

    $\begingroup$ If you think that collaboratively editing a document would suit your purposes, there are tools for it. If you want use TeX in some chat client, you can find several solutions for that. This post discusses several other possible solutions. $\endgroup$ Sep 9, 2013 at 11:12

  • $\begingroup$ @Lord_Farin That's really excellent, so much so that I think you should offer it as an answer in its own right. $\endgroup$

If you are intending to communicate in real-time with a small(ish) group of people, MathIM.com provides you with an IRC-like client capable of rendering maths.

Alternative chat solutions are described here; it's just that I have good experience with MathIM myself.


For non-real-time communication, use $\LaTeX$ and distribute the resulting PDFs to the relevant people.


Martin Sleziak's comment contains pointers to threads with more options.

  • $\begingroup$ The "Quickie" option is really neat. I'll be talking about this around the department this week. Cool. $\endgroup$ Sep 15, 2013 at 18:52
