# 使用Typora添加数学公式 #

## 1. 打开Typora选择数学模块 ##

*  点击“段落”—>“公式块”
 *  快捷键Ctrl+Shift+m
 *  “$$”+回车

以上三种方式都能打开数学公式的编辑栏，如下：  
![这里写图片描述][70]

## 2. 添加数学公式 ##

输出美观规范的数学公式，要清楚它们的格式和代码，在编辑栏中输入代码，对应的公式会在下面实时显示，如：

## 3. 常用公式的代码 ##

补充：

### 花括号/行列式 ###

\\\[ c(u)=\\begin\{cases\} \\sqrt\\frac\{1\}\{N\}，u=0\\\\ \\sqrt\\frac\{2\}\{N\}， u\\neq0\\end\{cases\} \\\\ c(u)=\\begin\{vmatrix\} \\mathbf i & \\mathbf j \\\\ \\partial x & \\partial \\end\{vmatrix\} \\\]

c(u)=\begin{cases} \sqrt\frac{1}{N}，u=0\\ \sqrt\frac{2}{N}， u\neq0\end{cases}
    \\
    c(u)=\begin{vmatrix} \mathbf i & \mathbf j \\ \partial x & \partial \end{vmatrix}

### 空格 ###

\\\[ a \\quad b \\\]

a \quad b
