\section*{Usage}

This is a template for compact cheat sheets. Read the code for customization options.

\subsection*{Headings}

Use the familiar \texttt{section}, \texttt{subsection}, \texttt{subsubsection} or their asterisk variants to outline your sheet.

\subsection*{Math mode}

Both inline formulas, like $\frac{1}{n-1} \sum_{i=1}^n (x_i - \mu)^2$, and display formulas, like
\[
  \frac{1}{n-1}\sum_{i=1}^n (x_i - \mu)^2
\]
work. We included the \texttt{amsmath} package, so e.\,g. \texttt{align} also works
\begin{align*}
  \mathbb E(X) &= \frac{1}{n} \sum_{i=1}^n x_i\\
  \operatorname{Var}(X) &= \frac{1}{n} \sum_{i=1}^n x_i^2
\end{align*}

\subsection*{Lists}

We use the \texttt{enumitem} package to make \texttt{itemize} lists more compact.

\begin{itemize}
  \item Item 1
  \item Item 2
  \begin{itemize}
    \item Item 2.1
    \item Item 2.2
    \begin{itemize}
      \item Item 2.2.1
      \item Item 2.2.2
    \end{itemize}
  \end{itemize}
  \item Item 3
\end{itemize}

\subsection*{Tables}

Use \texttt{tabularx} to make tables of full column width.

\begin{tabularx}{\columnwidth}{|c|X|}
  \hline
  1 & Entry 1\\
  2 & Entry 2\\
  \hline
\end{tabularx}


\end{multicols*}
