按照当前格式压缩乳胶文档？

Question

我正在尝试编写一个尽可能紧凑的乳胶文档，因为我被允许将一页纸带入我正在写的考试中（听起来有点搞笑，但我认为这在很多情况下都适用），所以我真的想让我的文档尽可能紧凑。我不在乎它的字体是否微小，只要我能仔细阅读它。目前我想到以下几点，

    \documentclass{article}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage[margin=0in,top=0in,bottom=0in]{geometry}
\usepackage{amsmath}
\begin{document}
\fontsize{5}
Some theorem will go here. some math equation $\text{taylor series = } \sum_{k=0}^{n}\frac{f^(k)(x)(x-a)^{k}}{k!}$ and some more theorems. But I think the general idea is conveyed that I want this to be compact as possible. 

\end{document}

有人对此还有其他建议吗？如果我可以使其更加紧凑，我将不胜感激，因为我试图在那一页上放很多东西。

这是我目前拥有的：

谢谢

该savetrees包节省了一些额外的空间：

\documentclass{article}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}

\usepackage[margin=0in,top=0in,bottom=0in]{geometry}
\usepackage{amsmath}
\usepackage{savetrees}


\begin{document}
\fontsize{5pt}{5pt}\selectfont
Some theorem will go here. some math equation $\text{taylor series = } \sum_{k=0}^{n}\frac{f^(k)(x)(x-a)^{k}}{k!}$ and some more theorems. But I think the general idea is conveyed that I want this to be compact as possible. 

\end{document}
