考虑:
\documentclass[12pt,a4paper,oneside]{book}
\usepackage{amsfonts, graphicx, verbatim, mathtools,amssymb, amsthm, mathrsfs,amsmath}
\usepackage{multicol}
\begin{document}
\begin{itemize}
\item $\lim_{t\rightarrow \infty} \frac{1}{t} \phi(t)=0, \quad \lim_{t\rightarrow \infty} \frac{1}{t} \phi^2(t)=0, \quad \lim_{t\rightarrow \infty} \frac{1}{t} S(t)=0, \quad$
\item two.
\item three.
\end{itemize}
\end{document}
我怎样才能将 $t\rightarrow \infty$ 置于 $\lim$ 之下?
答案1
最好使用\to
而不是\rightarrow
。在此视图中,代码
\documentclass{article}
\usepackage{amsfonts, graphicx, verbatim, mathtools,amssymb, amsthm, mathrsfs,amsmath}
\usepackage{multicol}
\begin{document}
\begin{itemize}
\item $\lim\limits_{t \to \infty} \frac{1}{t} \phi(t)=0,
\quad \lim\limits_{t \to \infty} \frac{1}{t} \phi^2(t)=0,
\quad \lim\limits_{t \to \infty} \frac{1}{t} S(t)=0, \quad$
\item two.
\item three.
\end{itemize}
\end{document}
