MathJax Cheatsheet

This is a cheat sheet on which code leads to which output.

When using inside Obsidian.md the code representing the MathJax formular needs start and end with the dollar sign, i.e.: $a_1..a_n$

Matrix

\begin{pmatrix}
 & ​Bob & Alice \\\ 
Bob & 0 & 1 \\\ 
​Alice & 1 & 0  
\end{pmatrix}
