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.
