%% Build this document with

%% or

%%   dvips annotated_homework_example.dvi
%%   ps2pdf annotated_homework_example.ps

%% The result will be annotated_homework_example.pdf.

%% IMPORTANT NOTE: Because this sample uses cross references, you must
%% build it *TWICE*. LaTeX finds all of the cross reference TARGETS first
%% and then, on the second run, plugs them all in to the appropriate
%% places.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% PREAMBLE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% Every LaTeX document starts with a \documentclass line. The
%% document class sets up the most prominent features of the document
%% style (e.g., page styles, font, etc.).
%%
%% Standard document classes include article, book, and report.
%%
%%   *) The article document class is the most commonly used for short
%%      documents. It provides sectioning commands and flexible titling
%%      options.
%%
%%   *) The report document class gives you chapters and puts the title
%%      information centered on a separate unnumbered page.
%%
%%   *) The book document class gives you the ability to make parts and
%%      chapters and is usually used in two-sided printing mode (e.g.,
%%      page numbering alternates from being on the top left to top
%%      right of the page rather than in the bottom center).
%%
%% More advanced document classes include memoir, which is a drop-in
%% replacement for the standard classes that has many other features as
%% well. It folds in a rich feature set from some of the most popular
%% packages (packages are explained below).
%%
%% Optional arguments to LaTeX macros come in square brackets. In this
%% case, [10pt] tells the article class that we want 10 point font.
\documentclass[10pt]{article}

%% The default margins for article may seem large to you. They are
%% designed to look pleasant on a page. To use 1 inch margins instead,
%% call the geometry package with this line:
\usepackage[margin=1in]{geometry}

%% The enumitem package provides nicer list support to LaTeX.
\usepackage[shortlabels]{enumitem}

%% This setcounter line makes it so that \section commands do not have
%% numbers printed in front of them. Delete this line ENTIRELY *OR*
%% change the 0 to 1 or higher to make it so that \section commands
%% automatically get numbered.
%%
%% If you do increase the 0 to a positive integer or remove this line
%% entirely, later you can use \section* to get a single unnumbered
%% section.
\setcounter{secnumdepth}{0}

%% Here, we use the fancyhdr and lastpage packages to customize the
%% header and footer of each page
\usepackage{fancyhdr, lastpage}
\pagestyle{fancy}
\fancyhf{}
%
%% Put your name and homework identification here

%% These next two lines are only used if you are going to cross
%% reference equations in your submissions. They can probably be removed
%% for 481 submissions.

%%%%%%%%%%%%%%%%%%%%%%%% MAIN DOCUMENT CONTENT %%%%%%%%%%%%%%%%%%%%%%%%%

% We surround our main content with a ``document'' ``environment.'' This
% marks the end of our LaTeX setup and the start of our document output.
%
% All ``environments'' are identified by \begin{...} and \end{...}
% macros.
\begin{document}

% This is a note about running LaTeX twice. It's centered, 3/4 the width
% of the printed type block, and it has a box around it. You can remove
% it.
\centerline{\fbox{\parbox{0.75\columnwidth}{\textbf{SPECIAL NOTE:} If
you notice a few ``\textbf{??}'' in funny places in your document (e.g.,
the footer may say ``\textbf{Page 1 of ??}''), then run \LaTeX{} again.
That information was not available in the first pass, but it will be
filled in properly in the second pass.}}}

% Creates a section header with ``Chapter 2 Questions'' in it
\section{Chapter 2 Questions}

% Creates a list
\begin{itemize}

        % Pass optional items in square brackets to each \item macro.
        % Those optional items get displayed as the label for that item.
        \item[2.1.] Here is my answer to question~2.1 of the text of the
                book. This question has sub-parts, and so I use another
                list to answer them.
                %
                % An enumerate list will automatically count each item
                % for you. Pass it the type of label you want (e.g., 1.
                % or a) or i) or ...). See below for another example.
                \begin{enumerate}[a)]

                        \item Answer to first sub-part.

                        \item Answer to second sub-part.

                \end{enumerate}

        \item[2.7.] Here is my answer to question~2.7. It also has
                sub-parts, but for some reason they're given with roman
                numerals, and so I'll use lowercase roman numerals here
                too.
                %
                % Here's another example. This time we use lowercase
                % roman numeral counting.
                \begin{enumerate}[i)]

                        \item Answer to first sub-part.

                        \item Answer to second sub-part.

                \end{enumerate}

\end{itemize}

% Creates a section header with ``Chapter 3 Questions'' in it
\section{Chapter 3 Questions}

\begin{itemize}

        \item[3.2.] Question~3.2 asks me to list things, and so I give
                an unnumbered/unlettered list.
                %
                % Itemize gives us unnumbered lists. Without an optional
                % argument, each item displays a symbol corresponding to
                % how deep the current list is.
                \begin{itemize}

                        \item First item in the list.

                        \item Second item in the list.

                        \item Third item in the list.

                \end{itemize}
                %
                I also say something after the list.

        \item[3.15.] Strangely, question~3.15 requires me to list a
                mathematical equation.
                %
                % Math is very nice to typeset in LaTeX.
                \begin{equation}
                        \frac{\sin(2\pi T)}{2\pi}
                        =
                        \int_0^T \cos(2\pi t) dt
                        \label{eq:trigcalc}
                \end{equation}
                %
                % You can refer to equations automatically (i.e., you
                % don't have to keep track of equation numbers).
                However, you probably don't need
                Equation~\ref{eq:trigcalc} in ECE~481.
