The MathJax is fine , but it is so complex to write integral and Sigma notations using it . Is there any other way to write these complex equations?

Btw I am on mobile often so it is hard to write code :-/

  • $\begingroup$ Perhaps you can have a look at the suggestions given in some older discussions here on meta, such as: WYSIWYG for math formulas?, MathJax WYSIWYG Editor or Is there an application where you can visually input LaTeX and have it translate to a code that works in Stack Exchange?. At the same time, writing some simple integrals and sums isn't that difficult once you get a bit of practice. (I guess it's easier on a desktop rather on some mobile device.) $\endgroup$ Feb 8 at 6:21

    $\begingroup$ What's complicated about writing \int_0^1f(x)\,dx to get $\int_0^1f(x)\,dx$? $\endgroup$ Feb 8 at 11:43

    $\begingroup$ @GerryMyerson I understand the OP. For example on the iOS English keyboard here, the $ and numbers is in one symbols page, while \ , _, and ^ is in another symbols page, and the letters is yet in another page. :-\\ $\endgroup$

  • $\begingroup$ @peter, OK, I understand. But unless it's possible to install some software that takes in "integral from zero to one of f(x) dx" and produces $\int_0^1f(x)\,dx$ I don't see what can be done. $\endgroup$ Feb 8 at 20:58
  • $\begingroup$ @peterwhy: The keyboards apps for mobile devices usually have to fit in many features in a small space so a little bit switching between pages of the app is necessary. After some time this becomes a habit. For me (MS SwiftKey on Android) the symbols (including dollar, plus, minus etc) appear using long press of alphabet keys and that's mostly sufficient for typical usage of mathjax. $\endgroup$
