Just as an aside, you really shouldn't use \$\$ ... \$\$ for display math in LaTeX, but \[ ...\]

It will prevent you from using the [fleqn] class option and will also mess up vertical spacing when using  the amsmath package.  See <http://www.tex.ac.uk/cgi-bin/texfaq2html?label=dolldoll> for some explanation or

texdoc l2tabu-en

for an explanation (plus a good list of other things you shouldn't do).
