# Math

If you want to display math equations in your presentation you can easily do so with the MathJax plugin. This is a very thin wrapper around the MathJax library. Find out more about plugins here.

The plugin defaults to using LaTeX but that can be adjusted through the math configuration object. Note that MathJax is loaded from a remote server. If you want to use it offline you'll need to download a copy of the library and adjust the mathjax configuration value.

Below is an example of how the plugin can be configured. If you don't intend to change these values you do not need to include the math config option at all.

<script src="plugin/math/math.js"></script><script>  Reveal.initialize({    math: {      mathjax: 'https://cdn.jsdelivr.net/gh/mathjax/mathjax@2.7.8/MathJax.js',      config: 'TeX-AMS_HTML-full',      // pass other options into MathJax.Hub.Config()      TeX: { Macros: { RR: "{\\bf R}" } }    },    plugins: [ RevealMath ]  });</script>
<section>  <h2>The Lorenz Equations</h2>  \begin{aligned} \dot{x} &amp; = \sigma(y-x) \\ \dot{y} &amp; = \rho x - y - xz \\ \dot{z} &amp; = -\beta z + xy \end{aligned}</section>

\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned}

## Markdown

If you want to include math inside of a presentation written in Markdown you need to wrap the formula in backticks. This prevents syntax conflicts between LaTeX and Markdown. For example:

$$J(\theta_0,\theta_1) = \sum_{i=0}$$
