For a semester-length course, all seven chapters can be covered. For a shorter course, the
book is designed so that chapters 1, 2, and 5 are the only ones that are required for conti-
nuity; any of the others can be included or omitted at the instructor’s discretion, with the only
constraint being that chapter 6 requires chapter 4.
