Quartz uses Katex by default to typeset both inline and block math expressions at build time.

## Syntax

### Block Math

Block math can be rendered by delimiting math expression with `$$`

.

```
$$
f(x) = \int_{-\infty}^\infty
f\hat(\xi),e^{2 \pi i \xi x}
\,d\xi
$$
```

$f(x)=∫_{−∞}f(^ ξ),e_{2πiξx}dξ$

$a =b+c=e+f $

$[1a 2b 3c ]$

### Inline Math

Similarly, inline math can be rendered by delimiting math expression with a single `$`

. For example, `$e^{i\pi} = -1$`

produces $e_{iπ}=−1$

### Escaping symbols

There will be cases where you may have more than one `$`

in a paragraph at once which may accidentally trigger MathJax/Katex.

To get around this, you can escape the dollar sign by doing `\$`

instead.

For example:

- Incorrect:
`I have $1 and you have $2`

produces I have $1andyouhave$2 - Correct:
`I have \$1 and you have \$2`

produces I have $1 and you have $2

## MathJax

In `quartz.config.ts`

, you can configure Quartz to use MathJax SVG rendering by replacing `Plugin.Latex({ renderEngine: 'katex' })`

with `Plugin.Latex({ renderEngine: 'mathjax' })`

## Customization

- Removing Latex support: remove all instances of
`Plugin.Latex()`

from`quartz.config.ts`

. - Plugin:
`quartz/plugins/transformers/latex.ts`
