Well it was bound to happen... I'm not completely happy with these units yet. In fact unit 4 (exponential funtions) has tremendous potential that I haven't tapped into yet. That is why several of those lessons were taken off line while they are being revised.
Remember that this is a first draft of a continuously evolving textbook! Eventually, I would like to see comments and revisions made by a community of users... so I doubt that the book will ever be completely "finished".
