# LaTeX

Typesetting mathematics with LaTeX can be frustrating. This page contains commonly needed, but surprisingly hard to find, LaTeX commands and procedures.

## Starring equations

Use the \tag command to change what \ref returns for a given equation.

\begin{align}
e^{\pi i} + 1 = 0
\tag{$*$}
\ref{euler}
\end{align}
