Mathematical Equations in epubs
If you have a technical book with many mathematical equations in word, what is the best way to convert the file into an epub. Should you save the word file as an earlier version to convert all the equations into images, or is there a way to bring the equations into the epub file as text by embedding a font?

If I have equations, I always convert them into a SVG via codecogs. That has the advantage that it can scale with the textsize with no loss to quality.

Yes, SVG is the best solution, so it scales with the font.

Of course, svg images are optimal but the problem with this method is that the OP should write again all the equations (and after that, to reembed them in the html file). If he were to start from zero, your advice is probably the most wise, but with the .doc file with the equations already written, I don't know if using the codecogs services if the better choice.

Automatic Equations for Whole Pages
Quote:
http://www.codecogs.com/latex/htmlequations.php It says that by adding a script to the header section of each page and tagging the equations with lang="latex" the equations are included as scalable graphic which can be formatted with css. I tried it out for a page and it seemed to work, even when offline.

But it will probably not work on a reader.

I'm working on the same problem.
I've coded the equations as LaTeX formulae out of force of habit. I'll probably retain the Latex for the pure ASCII version, use itex2MML to convert to MathML to futureproof it, and use pmml2svg to convert the MathML to SVG for an epub2 version. I might also use dvisvg to convert the LaTeX directly to SVG.
