\chapter{Appendix}
This is an example of an appendix. 
The only difference is the use of \verb+\appendix+ command at the start of this \texttt{tex} file. 
This automatically changes the chapter and section headings.

\section{A section}
The easiest method.

\begin{equation}\label{eq:sum}
    x_k = \frac{a_k+b_k}{2}
\end{equation}

\section{False Position}

\section{Starting the Appendices}
Actually, using appendices is quite simple.  Immediately after the end
of the last chapter and before the start of the first appendix, simply
enter the command \verb|\appendix|.  This will tell \LaTeX~to change
how it interprets the commands \verb|\chapter|, \verb|\section|,
\textit{etc.}

Each appendix is actually a chapter, so once the \verb|\appendix|
command has been called, start a new appendix by simply using the
\verb|\chapter| command.

Note that the \verb|\appendix| command should be called only
once--not before the start of each appendix.

All the fancy referencing and tools still work.
You only need to add the appendix command and all will be as it should be.
