MathJax是什么？

MathJax是一个JavaScript，用于在博客或其他html页面上渲染Latex、MathML的工具，由服务器端提供，可以在网页上显示公式。

1，安装MathJax，需要在本地安装MathJax的Javascript，以及wordpress里面的MathJax插件

MathJax-LaTeX

This plugin enables MathJax (http://www.mathjax.org) functionality for WordPress. Version 1.0 is compatible with MathJax 1.1 and the CDN.

Download Version 1.0

1. Unzip the downloaded .zip archive to the /wp-content/plugins/ directory
2. Download the MathJax Javascript library (http://www.mathjax.org/download/)
3. Place the Javascript library in the mathjax-latex directory (/wp-content/plugins/mathjax-latex/MathJax)
4. Activate the plugin through the 'Plugins' menu in WordPress
5. You can configure the plugin to load MathJax from a different URL to the default. See the options page.
6. Alternatively you can use the MathJax Content Distribution Network (http://www.mathjax.org/docs/1.1/start.html#mathjax-cdn) to deliver the Javascript,
   just tick the relevant box on the options page.

2，设置MathJax

要支持公式的引用需要修改MathJax的设置，参考http://zhiqiang.org/blog/it/mathjax-make-mathematics-beautiful.html

<script type="text/x-mathjax-config">
    MathJax.Hub.Config({
        TeX: {equationNumbers: {autoNumber: ["AMS"], useLabelIds: true}},
        "HTML-CSS": {linebreaks: {automatic: true}},
        SVG: {linebreaks: {automatic: true}}
    });
</script>

如何修改，参考http://www.mathjax.org/docs/2.0/platforms/index.html

3，wordpress中使用MathJax

显示效果，可以采用完全Latex的写法写下面的公式1：

\begin{equation}\label{eq1}r = r_F+ \beta (r_M - r_F) + \epsilon\end{equation}

得到：
