案例 範德蒙行列式:

\documentclass[11pt, A4paper]{article}
\usepackage[space,UTF8]{ctex}
\usepackage{graphicx}
\usepackage{amsmath}
\title{線性代數}
\author{tangkangqi}
\date{\today}
\begin{document}
%\maketitle
\part{範德蒙行列式}
\section{定理}

$$
\begin{vmatrix}
1		&1		&\cdots		&1\\
x_1		&x_2		&\cdots		&x_n\\
\vdots 	&\vdots 	&			&\vdots\\
x_1^{n-1}	&x_2^{n-1}	&\cdots 		&x_n^{n-1}\\
\end{vmatrix}
=
\prod_{1\le i<j\le n}{(x_i - x_j)}{\quad (n \ge 2)}
$$

\section{證明}

若$D_n$爲$n$階範德蒙行列式$(n \ge 2)$，則有
$$D_n = \prod_{1\le j < i \le n}{(x_i - x_j)}$$


這裏 
%\begin{equation}
$$
\begin{aligned}
\prod_{1\le j<i \le n}{(x_i - x_j)}
=
&(x_n - x_{n-1})(x_n - x_{n-2})...(x_n - x_1)(x_{n-1} - x_{n-2})(x_{n-1} - x_{n-3})...\\
&(x_{n-1} - x_{1})...(x_{3} - x_{2})(x_{3} - x_{1})(x_{2} - x_{1}).
\end{aligned}
\label{f2}
$$
%\end{equation}

\end{document}
