This is a cheat sheet on which code / markdown notation leads to which MathJax output.
MathJax is an open-source JavaScript display engine for LaTeX, MathML, and AsciiMath notation that works in all modern browsers.
MathJax in Obsidian.md
When using MathJax inside Obsidian.md the markdown code representing the MathJax formula needs start and end with the dollar sign, i.e.: $a_1..a_n$
In order to show fractions a little bit bigger and centered use two dollar signs, i.e.: $$a = \frac{\sqrt{b^2 + c^2}}{2}$$
Printing little bigger works too with $\displaystyle$
ahead of the fraction
