$ f(x) = a+b$
$$ f(x) = a+b$$
\begin{equation}
C_N=\beta t + \alpha.

??LateX代码中, & \& &用于分隔列,\用于分隔行.
\begin{equation}
\begin{bmatrix}
1 & 2 & \cdots \\
67 & 95 & \cdots \\
\vdots & \vdots & \ddots \\
\end{bmatrix}
\end{equation}
\begin{equation}
\alpha^{2} + \beta = \Theta
\end{equation}
??通过cases环境实现公式的组合,&分隔公式和条件,还可以通过\limits来让x→0位于lim的正下方而非默认在lim符号的右下方显示
\begin{equation}
D(x)=\begin{cases}\lim_{x\to0}\frac{a^x}{b+c},&x<3\\\pi,&x=3\\\int_a^{3b}x_{ij}+e^2\mathrm{d}x,&x>3&\end{cases}
\end{equation}
??通过split环境实现公式拆分.
\begin{equation}\begin{split}
\cos 2x &= \cos^2x - \sin^2x \\
&=2\cos^2x-1
\end{split}\end{equation}
\begin{align}
\left\{ %在equation环境下使用,用\left\{命令添加左大括号,用\right.以打点.结束

y&=eq2+1

\right.
\end{align}
\begin{numcases}{}
x_1&=eq1 \label{eqsystem1} \\
x_2+1&=eq2 \label{eqsystem2}
