FWIW, if anyone cares, I just posted the html version of this article to my web site.
http://home.pipeline.com/~hbaker1/FAQ-circumcircle.htm
Hopefully, it is more readable than the ascii version.
Neat! Now make (La-)TeX it and chuck it to arxiv, there web-interface works smoothly (as somemone stated on this list, and I can second that).
Note very carefully: due to the "head-to-tail" orientation of the vectors, the various vector products have surprising signs; e.g.,
a.b = -|a||b| cos C
Of course, even with traditional vectors, this is still true, but it looks really weird, and can easily trip you (& me!) up.
