\chapter{Test Appendix with a very long title in order to test spacing behavior} \label{app:test} \lipsum[2] A convenient form for representing substantial numerical or textual data is a table. Table~\ref{tab:test} shows an example of this functionality in \LaTeX. \begin{table} \centering \caption{Test table. With an extra-long caption to test spacing functionality for table captions. And inline mathematics.} \begin{tabular}{lrr} \toprule Heading 1 ($u_x$) & Head 2 & Head 3 \\ \midrule Analytical & 1.000 & 1.000 \\ Forward Difference & 0.973 & 0.976 \\ \bottomrule \end{tabular} \label{tab:test} \end{table} Diagrams, plots, and other graphics should be placed in figures. Figure~\ref{fig:test} shows an example of such an environment. The command \verb+\includegraphics+ from the \verb+graphicx+ package may be used to include external graphics in a wide variety of formats. \begin{figure} \centering \includegraphics[width=1in]{example-image-b} \caption{This test figure tests captions and Table of Contents behavior for lengthy captions.} \label{fig:test} \end{figure} \section{This is a Very Long Heading to Test the Table of Contents Behavior for Very Long Section Headings} Sample text.
