Math

Writing math equations in Markdown/MDX documents

Getting Started

Next Docs UI doesn't bundle with other plugins, you have to manually install those plugins.

npm install remark-math rehype-katex katex

Add Plugins

Add the remark/rehype plugins you have installed above.

Assume you're using the default contentlayer configuration:

import { makeSource } from 'contentlayer/source-files'
import { createConfig } from 'next-docs-zeta/contentlayer/configuration'
import rehypeKatex from 'rehype-katex'
import remarkMath from 'remark-math'
 
const config = createConfig(...)
 
config.mdx!.remarkPlugins!.push(remarkMath)
config.mdx!.rehypePlugins!.push(rehypeKatex)
export default makeSource(config)

Add Stylesheet

In order to make it looks great on the client, add the following to root layout:

import 'katex/dist/katex.css'

Done

Type some TeX expression in your documents

$c = \pm\sqrt{a^2 + b^2}$

c=±a2+b2c = \pm\sqrt{a^2 + b^2}

Long equations example

a1†=X−iY2⊗I⊗I⊗...⊗Ia2†=Z⊗X−iY2⊗I⊗...⊗I⋮a2n†=Z⊗Z⊗Z⊗...⊗X−iY2\begin{align} a^\dagger_1 &= \frac{X - iY} {2} \otimes I \otimes I \otimes ... \otimes I \\ a^\dagger_2 &= Z \otimes \frac {X - iY} {2} \otimes I \otimes ... \otimes I \\ &\vdots \\ a^\dagger_{2n} &= Z \otimes Z \otimes Z \otimes ... \otimes \frac{X - iY} {2} \end{align}
