Here are some examples of rendering mathematics equations with Dokuwiki.
This is a wiki that I set up for my own personal use, and for friends to use as well–to share anecdotes, add verbage, mess around, generally insult one another, etc. I absolutely reserve the right to delete the account of anyone I feel like. This wiki si generally publicy available, but that does not mean it is for the public to edit.
If you've never edited a wiki before, you need to check this out: http://wiki.splitbrain.org/wiki:syntax
other than that, you might want to start with me or good old Enoch Yeobright Penn
