数学公式

有时候需要罗列多个公式,可以用eqnarray*标签包围公式代码,在需要转行的地方使用\\,每行需要使用2个&来标识对齐位置,两个&...&号之间的是公式间对齐的位置,每行公式后可使用\tag{...}标签编号

1
2
3
4
5
6
$$
\begin{eqnarray}
x^n+y^n &=& z^n \tag{1.4} \\
x+y &=& z \tag{1.5}
\end{eqnarray}
$$

\[ \begin{eqnarray} x^n+y^n &=& z^n \tag{1.4} \\ x+y &=& z \tag{1.5} \end{eqnarray} \]

当想让字母出现在公式下方时使用\mathop{}

1
a = \mathop{argmax}_aF(a)

\[a = \mathop{argmax}_aF(a)\]
