% Welcome to overleaf, (formerly writeLaTeX) --- just edit
% your LaTeX on the left, and we'll compile it for you on
% the right. If you give someone the link to this page, they
% can edit at the same time. If you create a free overleaf
% account, all your projects will be saved. See the help
% menu above for more info. Enjoy!

% My thanks to Dana Ernst of Northern Arizona University
% for sharing his template with me. This is largely his work.

% This is all preamble stuff that you don't have to worry about.
% Head down to where it says "Start here"

Information about collaboration should go here. If you feel it is appropriate to include any other comments as an introduction, put it here too.
\begin{problem}{x.yz} %You can use theorem, exercise, problem, or question here. Modify x.yz to be whatever number you are explaining/proving.
Delete this text and write your statement here. Replace x.yz with the class's numbering convention for that item.
\end{problem}
\begin{proof}
Blah, blah, blah. Delete this and write your proof here.
\end{proof}
\begin{theorem}{w.xy}
This is a theorem about flying pigs.
\end{theorem}
\begin{proof}
Blah, blah, blah. This is another proof for you to delete. It has some math symbols in it: Let $\alpha \in (A \cup B) \cap \{\text{flying pigs}\}$ and $\mathbb{Z} \subset \mathbb{R}$.
% If you want to include a figure, you have to upload the image file to overleaf (or store it in the same folder as your .tex file, if you're not using overleaf). Here is the syntax:
%\begin{figure}[ht]
%\centering
%\includegraphics[width=.25\textwidth]{myimage.png}
%\caption{This is a picture of math.}
%\end{figure}
%After your figure you can have more text. It is possible to change the way your figure is placed and sized. Play around with the parameters to see what happens.
%By the way, when you make figures with GeoGebra, you can easily ``export" as a .png file. Then upload into overleaf.com using the ``files -- upload figures \dots'' menu item.
\begin{description}
\item[Case 1:] Suppose $x=\sin\theta$ ... thus pigs fly.
\item[Case 2:] Suppose $x \neq \sin\theta$ ... therefore, pigs fly.
\end{description}
Since in every case pigs fly, we have proven that pigs do fly.
\end{proof}

\small{Read-only document can be found online at \url{https://www.overleaf.com/lotasymbols}} %copy and paste the READ-ONLY URL of your document into this line. Then others with this pdf can also access the .tex file. Avoid editing or deleting the project once you've shared this URL. (create a copy of this project to start a revised version of the same.) I'll use this mostly when a result gets published to the online class journal.
