通用 LaTeX 数学公式语法手册
MathJax 是一款运行于 Web 浏览器当中的开源 JavaScript 数学符号渲染引擎,通过它可以方便的在现代 Web 浏览器当中显示数学公式,目前已经能够解析 LaTex
、MathML
等标记语言。MathJax 项目发源于 2009 年,目前由 NumFOCUS 基金会主持,并且得到了 MathJax 联盟的支持,该联盟是美国数学协会(AMS)和 工业与应用数学协会(SIAM)的共同合资企业。
LaTeX 是一种高质量的排版格式,可以生成复杂的表格与数学公式,是当前电子与数学出版行业的事实标准。本文以 Pandoc 作为 LaTex 渲染引擎(一款用于标记语言文档转换的命令行工具),分门别类的总结了撰写数学公式所需要经常使用到的 LaTeX 语法,方便写作相关科技类文章时随手查阅。

\int\_{}^{}
命令调用,双重积分符号采用\iint\_{}^{}
,以此类推,最高可以支持四重积分。
曲线积分可以使用 \oint
命令调用,但是 MathJax 并不支持该语法,因此在开启了 Unicode 扩展的前提下,可以改为采用 \unicode{}
命令调用:

开启 AMS 扩展包的情况下,会在部分环境的多行公式后自动编号; | \[ \begin{eqnarray} E = mc^2 \\ e^{i\pi}+1=0 \end{eqnarray} \] |

||
整个公式都不进行编号,可以使用{equation*} 、{eqnarray*} 环境;
|
\[ \begin{eqnarray*} E = mc^2 \\ e^{i\pi}+1=0 \end{eqnarray*} \] |
|
||
单个方程不进行编号,可以在指定方程后面添加\nonumber 命令;
|
\[ \begin{eqnarray} E = mc^2 \\ e^{i\pi}+1=0 \nonumber \end{eqnarray} \] |
|
||
个别公式出现或者不出现编号,可以在公式后使用\tag{} 或者\notag 命令;

使用\left. 和\right. 不显示某侧的括号; |
\(\left. \frac{A}{B} \right \} \to X\) | \left. \frac{A}{B} \right \} \to X |
注意:在 Markdown 当中使用 LaTeX 时,为了避免语法冲突,花括号
{}
必须采用\{

MathJax 3.0 取消了单行公式环境下\\

颜色
LaTeX 默认支持下面表格当中的文本颜色:
字体颜色
公式当中可以使用\color{options}{math}
调用颜色命令,第 1 个参数为颜色,第 2 个参数为公式内容:
符号 | LaTeX |
---|---|
\({\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1}\) | {\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1} |
背景颜色
文本环境中可以使用\colorbox{options}{text}
来调用背景颜色命令,第 1 个参数为颜色,第 2 个颜色为公式内容:
符号 | LaTeX |
---|---|
\(\colorbox{yellow}{Thistext}\) | \colorbox{yellow}{Thistext} |
该命令应用于数学环境当中时,需要在第 2 个参数加入$\displaystyle + 公式$
:
符号 | LaTeX |
---|---|
\[ \colorbox{yellow}{$\displaystyle \frac{a}{b}$} \] |
\colorbox{yellow}{$\displaystyle \frac{a}{b}$}
|
注意:在 Markdown 内联 LaTeX 公式
$...$
当中使用$\displaystyle + 公式$
语法时将会引发冲突,因此该语法仅用于多行公式$$...$$
。
RGB 颜色
通过使用\definecolor
命令可以自定义 LaTeX 公式的颜色:
符号 | LaTeX |
---|---|
\(\definecolor{mygreen}{RGB}{0,200,0} {\color{mygreen}e^{i \pi} + 1 = 0 }\) | \definecolor{mygreen}{RGB}{0,200,0} {\color{mygreen}e^{i \pi} + 1 = 0 } |
