Chapter 21,22 Suggested Problems

While homework will not be graded, it is essential practice for learning the material. Thus we have provided the accompanying list of homework problems selected from the textbook, grouped by topic. Our recommendation is to work some of the appropriate homework problems following each lecture to ensure that you fully understand the concepts and how to apply them. They also may form a useful basis for asking questions during section.

Coding for list:

  • Q = Question in textbook
  • P = Problem in textbook
  • S = Section in textbook
