So, one might rewrite the <code>\</code><code>caption</code> -example as: -<blockquote> - -<pre> -\caption[Energy: $E=mc^2$]{Energy: \[E=mc^2\]} -</pre> -</blockquote><p> -for, after all, even if you want display maths in a caption, you -surely don’t want it in the list of figures. -<p/>The case of footnotes is somewhat more complex; -“<a href="FAQ-ftnsect.html">footnotes in LaTeX section headings</a>” -deals specifically with that issue. -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=extrabrace">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=extrabrace</a> -</body> |
