Use bold face instead of red to mark minor corrections.
Email from David Welsh points out that equation 9.1 can be derived
using the Pythagorean distance formula and the law of cosines
from planar trigonometry
and does not require the law of cosines from spherical trigonometry.
This eliminated one of my complaints about Kenner's understatement
of the math requirement required to understand the book. David also
pointed out an error in the description of Diagram 3.1. He has the 2003
edition and says "it looks it's a reprint of the 1976 edition because the
errors which you listed on your website are also in the 2003 edition."

Expand the title from "Geodesic Math Errata" to "Geodesic Math: Errata
and Criticism" since I certainly do a lot of the latter. Minor edits
to introductory remarks.
