Math Formulas

Retype supports rendering math formulas written according to the LaTeX grammar. Internally, Retype is powered by $\KaTeX$ and supports all syntax of the library.

Math equations can be rendered inline by wrapping the equation in $ characters, or as separate blocks by fencing the equation in $$ characters.

Inline syntax

An inline math equation is wrapped in $ characters.

$\displaystyle \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$

This formula $\displaystyle \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$ is inlined with text.

Block syntax

A block math equation is wrapped with $$ characters. Block equations are center aligned when rendered to the finished page.

$$
\displaystyle {1 +  \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots }= \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1.
$$

$$ \displaystyle {1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots }= \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1. $$

LaTeX code highlighting

Math formula blocks can benefit from syntax highlighting by adding the latex language specifier to code blocks.
