% The following two environments (theorem, proof) are
% where you will enter the statement and proof of your
% first problem for this assignment.
%
% In the theorem environment, you can replace the word
% "theorem" in the \begin and \end commands with
% "exercise", "problem", "lemma", etc., depending on
% what you are submitting.

\begin{theorem}{(Page 4 $\#$ 6)}
For any metric space $E$, the entire space $E$ is an open set.
\end{theorem}
\begin{proof}
Replace this text with the details of your proof. Mathematical symbols go between dollar signs, like this: $E$, \emph{not} in plain text like this: E. If there are more symbols you want, such as $\in$, you can find them at\\ \url{http://detexify.kirelabs.org/classify.html}. If you want to set expressions or equations out from the text so that they are more readable (great idea!), put them between double dollar signs: $$|x-x_0| < \delta \implies |f(x)-f(x_0)| < \epsilon.$$
The small square marks the end of the proof.
\end{proof}
