\end{aligned}

f(x)=(x+1)2=x2+2x+1\begin{aligned} f(x) &= (x+1)^2\\\\ &= x^2 + 2x + 1 \end{aligned} 

f(x) = \begin{cases}

十二、声明宏

对于一些复杂但是只有少许不同的表达式，可以声明一个函数来调用，提高源码的可读性，减少出错

\def\macroname#1#2{
your command
}

宏允许带任意数量的参数（也可以不带参），必须是#1,#2,……这样的命名格式，同时注意再定义宏的时候注意让#1与\中间隔一个空格，否则会解析成#。再调用的时候格式为\macroname{x}{y}{z}，可以参考一下的例子

\def\Normal#1#2#3{
\frac{1}{\sqrt{2\pi}\ #3}\exp{[-\frac{(#1 - #2)^2}{2\ #3^2}]}
}
f(x)=\Normal{x}{u_1}{\sigma_1}\\
f(y)=\Normal{y}{u_2}{\sigma_2}\\

f(x)=12π σ1exp⁡[−(x−u1)22 σ12]f(y)=12π σ2exp⁡[−(y−u2)22 σ22]\def\Normal#1#2#3{ \frac{1}{\sqrt{2\pi}\ #3}\exp{[-\frac{(#1 - #2)^2}{2\ #3^2}]} } f(x)=\Normal{x}{u_1}{\sigma_1}\\ f(y)=\Normal{y}{u_2}{\sigma_2}\\ 

\def\EXP{
e^x = 1 + x + \frac{1}{2!}x^2 + \frac{1}{3!}x^3  + \cdots
}
\EXP

ex=1+x+12!x2+13!x3+⋯\def\EXP{ e^x = 1 + x + \frac{1}{2!}x^2 + \frac{1}{3!}x^3 + \cdots } \EXP

十三、其他

1、排版

公式居中：

E=mc^2\\

E=mc2E=mc^2\\

添加标签：

cos\theta+isin\theta=e^{i\theta}\tag{1.1}

cosθ+isinθ=eiθ(1.1)cos\theta+isin\theta=e^{i\theta}\tag{1.1}

E=mc2E=mc^2

等号对齐：

\begin{align}f(x)=&x-1\\=&(x-1)(x^2+x+1)\end{align}\\

f(x)=x−1=(x−1)(x2+x+1)\begin{align}f(x)=&x-1\\=&(x-1)(x^2+x+1)\end{align}\\ 

\begin{equation} \begin{split}
a &= b + c - d \\
  &= e - f \\
  &= g + h \\
  &= i
\end{split} \end{equation}\\

a=b+c−d=e−f=g+h=i\begin{equation} \begin{split} a &= b + c - d \\ &= e - f \\ &= g + h \\ &= i \end{split} \end{equation}\\

2、公式加方框行号

a2=b2+c2−2bccos⁡A\begin{equation} \boxed{a^{2}=b^{2}+c^{2}-2bc\cos A }\\ \end{equation}

{ \bbox[#EFF]{\boxed{\text{求导数: }y=\sin^2\left(\frac1x\right)-2^x.}}} 

\ldots \quad \cdots \quad \vdots \quad \ddots \quad \dotsc

…⋯⋮⋱…\ldots \quad \cdots \quad \vdots \quad \ddots \quad \dotsc

3、 求和符号下多行限制条件

		 k_0+k_1+\cdots=n}
		{A_{k_0}A_{k_0}\cdots}

∏k0,k1,…>0k0+k1+⋯=nAk0Ak0⋯\prod_{k_0,k_1,\ldots>0\atop k_0+k_1+\cdots=n} {A_{k_0}A_{k_0}\cdots}

4、上下标记

5、显示长方程

- 12x^2y^4 - 12xy^5 + 2y^6 - a^3b^3
\end{multline}

\begin{multline} p(x) = 3x^6 + 14x^5y + 590x^4y^2 + 19x^3y^3\\ - 12x^2y^4 - 12xy^5 + 2y^6 - a^3b^3 \end{multline}
