I have a figure in LaTeX with a caption to which I need to add a formula (equation*
or displaymath
environments). For example:
\documentclass[12pt]{article}
\begin{document}
\begin{figure}[tbph]
\begin{center}
%...
\end{center}
\caption{As you can see
\begin{displaymath}4 \ne 5\end{displaymath}
}
\label{fig:somefig}
\end{figure}
\end{document}
This makes pdflatex angry, though it will produce a PDF.
! Argument of \@caption has an extra }.
<inserted text>
\par
l.9 }
What's the right way to go about adding an equation to a figure caption?
NOTE: Please do not suggest simply using the $ ... $
math environment;
the equation shown is a toy example; my real equation is much more intricate.
