Hi all,

The use of Illustator is a bit tricky here: I don't have that program.

Here's what I do, YMMV.

1) Create a latex file for each formula, e.g.

\documentclass[12pt]{article}
%% your style files, amsmath comes to mind
\pagestyle{empty}
\begin{document}

\begin{equation*}
2 + 2 = 5 \qquad\text{G. Orwell, 1984}
\end{equation

\end{document}

2) run file through normal latex
3) run dvi through dvips, with the following options:
dvips -Ppdf -E -o formula.eps formula.dvi
4) run eps-file through the epstopdf script.
epstopdf formula.eps

There you have it. The drawbacks are: only one formula per file, needs to use
the cmd-line. Advantage: no need for illustator.

Of course I assume you have teTeX installed and GhostScript. If you have other
tools, you may want to use those. If someone knows a way of skipping the latex
dvips step (i.e. an option for pdflatex to generate epdf directly, I'd like to
hear.
