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 |
|---|---|---|
$\min\limits_{x,y} f(x,y)$ |
Put limits directly under previous symbol \min
|
|
\emptyset |
Empty (Null) set | |
E \cup F, E \cap F |
Set union, intersection | |
\mathbf{x} |
Indicate x is a vector | |
\mathbb{R}, \mathbb{C} |
Number systems / sets (Real numbers set, Complex numbers) |
