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。

maupassant-hexo的数学函数开启方式

其他的主题可能方式不一样 具体需要对照文档

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.

$
\\beta
\\alpha
$

效果如下:
$
\beta
\alpha
$

或者这样以居中显示:

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

\[\beta \alpha\]
