Suggested Practice at Home to Supplement the Online Homework
Spring 2014
You are responsible for the skills
contained in these problems.
Priorities:
1. Rework lecture examples and recopy lecture materials.
2. Do the Online HW problems that are assigned for each section
inside of WebAssign.
3. Work the extra textbook examples below to cover all the skills
necessary for success. This provides you depth and breadth of
mathematical knowledge.
4. If you are short on time, you can always rework the examples
contained in the “text” of the textbook.)
Answers to Odd-Numbered HW Problems are found at the
back of your book in Appendix III starting on page A–11.
