TeXfilter

This is a simple filter module to embed TeX-generated images into Drupal nodes, which is very useful for embedding complex math formulas in pages without making images by hand and uploading them to Drupal.

It uses tags to automatically generate a PNG image based on the embedded TeX code. It also has rudimentary support for FCKEditor/HTMLArea integration. For Windows users, TeXaide (freeware) is a nice equation editor that will generate TeX automatically and can also work alongside MS Office's Equation Editor.
