Math Equations

Mathematical equations can be rendered using KaTeX.

Usage

Please read KaTeX documentation for more details.

Inline

Write inline math equations by wrapping LaTeX equations between $:

Let $f:[a,b] \to \R$ be Riemann integrable. Let $F:[a,b]\to\R$ be $F(x)=
\int_{a}^{x}f(t)dt$. Then $$F$$ is continuous, and at all $x$ such that $f$ is continuous at $x$, $F$ is differentiable at $x$ with $F'(x)=f(x)$.

Let f:[a,b]โ†’Rf:[a,b] \to \R be Riemann integrable. Let F:[a,b]โ†’RF:[a,b]\to\R be F(x)=โˆซaxf(t)dtF(x)= \int_{a}^{x}f(t)dt. Then FF is continuous, and at all xx such that ff is continuous at xx, FF is differentiable at xx with Fโ€ฒ(x)=f(x)F'(x)=f(x).

Blocks

For equation block or display mode, use line breaks and $$:

$$
I = \int_0^{2\pi} \sin(x) dx
$$
I=โˆซ02ฯ€sinโก(x)dxI = \int_0^{2\pi} \sin(x) dx

Configuration

To enable KaTeX, you need to install remark-math and rehype-katex plugins.

npm install --save remark-math@3 rehype-katex@4 hast-util-is-element@1.1.0
caution

Use the exact same versions. The latest versions are incompatible with Docusaurus 2.

Import the plugins in docusaurus.config.js:

const math = require('remark-math');
const katex = require('rehype-katex');

Add them to your content plugin or preset options (usually @docusaurus/preset-classic docs options):

remarkPlugins: [math],
rehypePlugins: [katex],

Include the KaTeX CSS in your config under stylesheets:

stylesheets: [
{
href: "https://cdn.jsdelivr.net/npm/katex@0.13.11/dist/katex.min.css",
integrity: "sha384-Um5gpz1odJg5Z4HAmzPtgZKdTBHZdw8S29IecapCSB31ligYPhHQZMIlWLYQGVoc",
crossorigin: "anonymous",
},
],

Overall the changes look like:

docusaurus.config.js
const math = require('remark-math');
const katex = require('rehype-katex');
