我无法解决写入系统方程自定义大小。
代码在这里。但我的系统方程很大,如下图所示:
\documentclass[11pt]{book}
\usepackage[T2A]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[mongolian]{babel}
\usepackage[b5paper, margin=2cm]{geometry}
\usepackage{amsmath,array,amssymb,systeme}
\setlength{\parskip}{1.5em}
\renewcommand{\baselinestretch}{1.8}
\begin{document}
$
\begin{cases}
it's \ cases \ 1\\
sample 2
\end{cases} $
$\left\{
\begin{array}{rl}
it's \ array \ 1\\
sample 2
\end{array} \right.
$
\end{document}
