\section{Introduction}

Welcome to the running example!

\section{Body}

\citet{Knuth1986} designed \TeX\ to integrate scientific notation with exposition. Then, the \LaTeX\ doc prep system \citep{Lamport1986} combined \TeX\ with several doc classes.

\begin{figure}[h]
\includegraphics[width=.9\textwidth]{mtcars-plot}
\caption{Fuel efficiency by weight and cylinderage in the {\it Motor Trends} dataset}
\label{fig:mtcars}
\end{figure}

Look at Figure~\ref{fig:mtcars}!

This is \verb|verbatim| code.

So is
\begin{verbatim}
this.
\end{verbatim}

This is \(\mathbb{R}\).

So is \[\mathbb{R}.\]

\[E(\rho\times\frac{1}{1+\frac{1}{2}})\]
\[E\left(\rho\times\frac{1}{1+\frac{1}{2}}\right)\]
\[E\Big(\rho\times\frac{1}{1+\frac{1}{2}}\Big)\]
\[E\left\{\rho\times\frac{1}{1+\frac{1}{2}}\right\}\]
\[E\left\langle\rho\times\frac{1}{1+\frac{1}{2}}\right\rangle\]

Use \(A\tr\) to denote the transpose of matrix \(A\).

Here's some math: \(\sum\)

\section*{Tables}

Here's an inline table:
\begin{tabular}{ccc}
one & two & three \\
a & 1 & \{Fred\} \\
b & 2 & (Pedro)
\end{tabular}
See? It's inline!
