Formulae in figures were a problem in version 0.1 and 0.2. Test wheather they work now in Fig.~\ref{fig:example}. \begin{figure} \centering Test \caption{Here we have formulae $\alpha$, $\beta$, $\vec{a}$.\dots} \label{fig:example} \end{figure} \subsection{Allowed \texttt{amsmath} environments} The \verb|align| environment is part of \verb|amsmath.sty| and therefor works, too: \begin{align} \sin^2x + \cos^2x &=1\,,\\ \tan\alpha &= \frac{\sin\alpha}{\cos\alpha}\,. \end{align} \verb|equation| is redefined and allowed: \begin{equation} \sin^2x + \cos^2x = 1\,. \end{equation} \verb|equation*| is defined by \verb|amsmath.sty| and allowed: \begin{equation*} \sin^2x + \cos^2x = 1\,. \end{equation*} \verb|gather|: \begin{gather} \sin^2x + \cos^2x =1\,,\\ \tan\alpha = \frac{\sin\alpha}{\cos\alpha}\,. \end{gather} \verb|gather*|: \begin{gather*} \sin^2x + \cos^2x =1\,,\\ \tan\alpha = \frac{\sin\alpha}{\cos\alpha}\,. \end{gather*} \verb|multiline|: \begin{multline} \sin^2x + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 \\ + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + \cos^2x =1\,. \end{multline} \verb|multiline*|: \begin{multline*} \sin^2x + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 \\ + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + \cos^2x =1\,. \end{multline*} \verb|\[| is redefined and works: \[ \sin^2x + \cos^2x = 1\,. \] \subsection{Forbidden \TeX\ and \LaTeX\ environments} \verb|eqnarray| is forbidden: \begin{eqnarray} \sin^2x + \cos^2x &=& 1\,. \end{eqnarray} \verb|eqnarray*| is also forbidden: \begin{eqnarray*} \sin^2x + \cos^2x &=& 1\,. \end{eqnarray*} Same for \verb|displaymath|: \begin{displaymath} \sin^2x + \cos^2x = 1\,. \end{displaymath} And of course \verb|$$| (thanks to David Kastrup): $$ \sin^2x + \cos^2x = 1\,. $$ \end{document}
