Latex 的一大优点就是其可以写出优美的数学公式，本博客也使用 MathJax 来得到 Latex 中数学公式的效果。但是由于其有自己的语法，所以写了这篇文章以整理数学公式相关的内容。
由于本文中公式较多，所以可能需要些许渲染的时间。

分数
分数最普通的形式为\frac{x}{y}，也可以用\tfrac{x}{y}来得到较小的分数。
\[\frac{x}{y}\ \ \tfrac{x}{y}\]
用\frac{x}{1+\frac{y}}可以得到连分数，但是使用\cfrac代替可以得到更大的分数。
\[\frac{2}{c + \frac{2}{d + \frac{2}{4}}} \ \ \cfrac{2}{c + \cfrac{2}{d + \cfrac{2}{4}}}\]
矩阵
矩阵首尾以\begin{matrix}和\end{matrix}标记，各元素以&分隔，以\\换行。

| \begin{matrix}
a_{11} & \cdots & a_{1n} \\
\vdots & \ddots & \vdots \\
a_{n1} & \cdots & a_{nn}
\end{matrix}
|
如上则是一个矩阵的代码，可以得到如下的效果。
\[\begin{matrix}
a_{11} & \cdots & a_{1n} \\
\vdots & \ddots & \vdots \\
a_{n1} & \cdots & a_{nn}
\end{matrix}\]
此外对于{matrix}中 matrix 可以替换成如下内容，以得到不同的边框。

| pmatrix |
\(\begin{pmatrix}a & b \\c & d\end{pmatrix}\) |
smallmatrix |
\(\begin{smallmatrix}a & b \\c & d\end{smallmatrix}\) |
分段函数 & 方程组
首尾以\begin{cases}和\end{cases}标记，各元素以&分隔，以\\换行。

| f(x) =
\begin{cases}
x, & x\ge0 \\
-x, & x<0
\end{cases}
|
可以得到如下效果。
\[f(x) =
\begin{cases}
x, & x\ge0 \\
-x, & x<0
\end{cases}\]
如下所示，可以对上面的稍加修改，
1
2
3
4
| \begin{cases}
x+y=1 \\
3x+4y=5 \\
\end{cases}
|
便可以得到方程组的形式。
\[\begin{cases}
x+y=1 \\
3x+4y=5 \\
\end{cases}\]
多行等式
首尾以\begin{align}和\end{align}标记，各元素以&分隔，以\\换行。

4
| \begin{align}
(x+y)^3 & = (x+y)^2(x+y)
& = (x+y)(x+y)(x+y)
\end{align}
|
实际效果如下。
\[\begin{align}
(x+y)^3 & = (x+y)^2(x+y)\\
& = (x+y)(x+y)(x+y)\\
\end{align}\]
