之前输入数学公式的一直用截图自觉用户体验很差，最近发现用的这个主题带了好用的数学函数辅助，便一发不可收拾。顺便推荐一下我用的主题是maupassant-hexo github ,这里记录一下数学符的用法。

Math Equation

Add

mathjax: true
in Hexo's _config.yml.

In the post which you would like to use math equation, add mathjax: true in the front-matter. For example:

title: Test Math
date: 2016-04-05 14:16:00
categories: math
mathjax: true
---
The default math delimiters are $$...$$ and \\[...\\] for displayed mathematics, and $...$ and \\(...\\) for in-line mathematics.

However, if your post contains dollar signs ($), and they appear often in non-mathematical parts, in other words, you want to use $ as dollar sign not inline math delimiter, please add

mathjax2: true
in Hexo's _config.yml instead of mathjax: true. Correspondingly, add mathjax2: true to the front-matter of the post in which you would like to use math equation.

See the example.

添加标签则可用

$
    \\beta
    \\alpha
$

效果如下： βα��

或者这样以居中显示：

\\[\\beta \\alpha\\]

βα��
