Homework
assignments and even-numbered answers
These are just suggested
problems. You can always try to work
others. Remember the answers to the odd problems are at the end of the
book. You should be able to work any
problem marked with one box without difficulty, so try those if you are having
difficulty with the suggested list. If
you are unable to solve those easier problems, then a visit to my office for
some help may be in order. Problems in
red are additions to the list you were given at the beginning of the
semester. You should always do the
multiple choice questions and the conceptual questions (CQ) for each chapter.
