Many of the following images (gleaned from the WWW and believed all to be freely usable for non commercial use) are used in this text. If any reader has better versions, the author would be pleased to hear of them.

Several of the images are from the excellent and extremely useful transparent GIF math symbol collection created by Karen M. Strom , which is documented at at the Amherst Campus of the University of Massachusetts, and is also available in compressed form from Karen has copyrighted her graphics as follows: "If you are an educational or non-profit organization, please feel free to use them in your documents.
