The following text files correspond to the video presentations. They offer problems and completely worked-out
and explained solutions. In addition you will find supplementary topics included in both the problems and solutions material.
We wish to acknowledge the support of the Gabriella
and Paul Rosenbaum Foundation in helping us develop the content on this website. Without the support of the Foundation
and its president, Madge Goldman, much of the material that will be posted here would not have existed.
