# 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.

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.

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.

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

\bigg\{ \;\mathbb{F}[x]\text{-modules } V\; \bigg\}
\longleftrightarrow
\bigg\{ \substack{\text{$\mathbb{F}$-vector spaces $V$ with a}
\\ \text{linear map $T : V \rightarrow V$}} \bigg\}
