MathJAX NOTES

Reference: MathJAX Macros table - macros start with \. Github Markdown allows a limited subset of MathJAX and no MathJAX extensions can be used. But in static site generators, extensions can be installed using <script> tag.

Inline expressions are written within $ $, block expressions within $$ $$. Curly Brackets { } are required for grouping multiple symbols where otherwise only a single character/symbol is expected

• eg. after _ (superscript under) and ^ (power/subscript over).

Notably MathJAX rendered by ChatGPT is a slightly different dialect - eg. it uses ( ) delimiters for inline expressions and [ ] for block expressions.

Some common function usages are:

MathJAX Code	Rendered Output	Description
$\min\limits_{x,y} f(x,y)$	$\min\limits_{x,y} f(x,y)$	Put limits directly under previous symbol \min
\emptyset	$\emptyset$	Empty (Null) set
E \cup F, E \cap F	$E \cup F, E \cap F$	Set union, intersection
\mathbf{x}	$\mathbf{x}$	Bold font: (my convention) x is a vector
\mathbb{R}, \mathbb{C}	$\mathbb{R}, \mathbb{C}$	Blackboard font: (my convention) Real numbers set, Complex numbers, etc.
\mathcal{N}	$\mathcal{N}$, $\mathcal{U}$	Calligraphic font: (my convention) Normal, Uniform distributions
