只需增加数学符号的大小

我想扩大整个文档的“仅数学符号”。但是该怎么做呢？

我的代码：

\documentclass[11pt,addpoints]{exam}
\usepackage{amsfonts,amssymb,amsmath, amsthm}
\usepackage{systeme}
\usepackage{mathrsfs}
\firstpageheader{Sample Exam (\numpoints\ points)\\ September 26, 2019}{}{Name: \underline{\hspace{2.5in}}}
\runningheader{Sample Exam}{}{Page \thepage\ of \numpages}
\runningheadrule

\begin{document}
\begin{questions} 

\fullwidth{\emph{Math mode} is used to display $x+y$ mathematical content in \LaTeX, and there are two main forms of math mode $x^2-y^2$: \emph{display mode} and \emph{inline mode}.  Question~\ref{DisplayModeExample} uses \emph{display mode}, which centers the math $sinx-2x$ content on its own line.  Question~\ref{InlineModeExample} uses \emph{inline mode} to render the math content within a line of text.}

\question[10] \label{DisplayModeExample}
Find an equation for the tangent line to the following curve at the point (0,1).
\[2xy^3 + y^4 = 1 + x^3y\]
\end{questions}
\end{document}

答案1

11pt该选项的默认正常尺寸为

 \DeclareMathSizes{10.95}{10.95}{8}{6}

也就是说，如果文本字体为 10.95pt，则数学文本大小使用 10.95pt，脚本使用 8pt，脚本脚本大小使用 6pt

所以之前：

在此处输入图片描述

后：

在此处输入图片描述

\RequirePackage{fix-cm}
\documentclass[11pt,addpoints]{exam}
\usepackage{amsfonts,amssymb,amsmath, amsthm}

\runningheader{Sample Exam}{}{Page \thepage\ of \numpages}
\runningheadrule

     \DeclareMathSizes{10.95}{15}{12}{10}
