WinEdt && LaTex（三）—— 宏包

• amsmath：最常用的数学宏包

1. bm：bold math 数学字体加粗

\documentclass{article}
\usepackage{bm}
\begin{document}
\[
\int k\,\mathrm{d}x \ne
\bm{\int k\,\mathrm{d}x}
\]
\end{document}

2. graphicx

\newcommand{\indep}{\rotatebox[origin=c]{90}{$\models$}}
$X \indep Y$

3. extpfeil/extarrows：xlongequal

\usepackage{extarrows}
\begin{equation}
a\xlongequal[abc]{def}b
\end{equation}

• 等于号下是abc，等于号上是def
