% Put the sticky note in a wrapfigure to have text wrap around it.

This text is \emph{important}. Here is an useful equation:

Here is some more text. This is useful information you need to know:
\begin{itemize}
\item sin approximation valid \textbf{only} for small angles
\item 2 radians is \textit{not} a small angle
\end{itemize}
