1. 如何输入括号和分隔符

()

、

[]

和

|

表示自己，

{}

表示

{}

。当要显示大号的括号或分隔符时，要用

\left

\right

命令。

例子：

$$f(x,y,z) = 3y^2z \left( 3+\frac{7x+5}{1+y^2} \right)$$

,显示：

\[f(x,y,z) = 3y^2z \left( 3+\frac{7x+5}{1+y^2} \right)\]

有时候要用

\left.

或

\right.

进行匹配而不显示本身。

$$\left. \frac{ {\rm d}u}{ {\rm d}x} \right| _{x=0}$$

\[\left. \frac{ {\rm d}u}{ {\rm d}x} \right| _{x=0}\]

1.1 偏导

$$\frac{\partial^{2}y}{\partial x^{2}}$$

\[\frac{\partial^{2}y}{\partial x^{2}}\]
