## Math Typesetting

A brief guide to setup KaTeX

Mathematical notation in a Hugo project can be enabled by using third party JavaScript libraries.

In this example we will be using KaTeX

- Create a partial under
`/layouts/partials/math.html`

- Within this partial reference the Auto-render Extension or host these scripts locally.
- Include the partial in your templates like so:

```
{{ if or .Params.math .Site.Params.math }}
{{ partial "math.html" . }}
{{ end }}
```

- To enable KaTex globally set the parameter
`math`

to`true`

in a project’s configuration - To enable KaTex on a per page basis include the parameter
`math: true`

in content files

**Note:** Use the online reference of Supported TeX Functions

### Examples

Inline math: \(\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…\)

Block math: $$ \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } } $$
