Editor Help

The editor toolbar is designed for frequent used markup operations. For example, to make a bulleted list, you can select the lines in the editor you want to turn into a bulleted list and click the Bulleted List submenu under the Text menu. The editor will automatically add the itemize environment and the item command at the beginning of each line.

\section{Formula}
For inline formulas, enclose the formula in \$…\$. For displayed formulas, use \$\$…\$\$. 
Here is an example of an inline formula: $x^2 + y^2 = z^2$.

\section{Numbering and referencing}
For any real number $x$, we have
\begin{align}
\exp (ix)& =\sum _{k=0}^{\infty }{\frac {(ix)^{k}}{k!}}\label{eq:1}\\
& = \cos x+i\sin x.\label{eq:2}
\end{align}
The equation \eqref{eq:1} is the power series definition of the exponential function, and the equation \eqref{eq:2} is known as Euler's formula.

\section{Theorem environment}
\begin{theorem}[Fermat's Last Theorem]
    \label{thm:fermat}
    No three positive integers $a$, $b$, and $c$ satisfy the equation $a^n + b^n = c^n$ for any integer value of $n$ greater than $2$.
\end{theorem}
\begin{proof}[Fermat's lost proof]
    I have a proof of this theorem, but there is not enough space.
\end{proof}

\section{Citation}
Einstein's journal paper \cite{einstein} and Dirac's book \cite{dirac} are physics-related items.
