Homework assignments are designed to help you study the material covered in lecture and learn how to apply the lecture information to problem solving situations. It is critical that you understand not only how to solve a particular problem, butwhy that method works. In this way, you will be able to apply the concepts involved in one problem to a variety of new types of problems. Due dates of assignments will be posted here and announced in class. A homework assignment will consist of: 1) Reading the text 2) Doing assigned sample problems. 3) Doing assigned exercises at the end of the chapter on your own and checking the answers in the Solutions Guide. 4) Handing in specific assigned problems.
Both the "sample exercises" and the "on your own" exercises are assigned to help you study and understand lecture material. Do as many "on your own" exercises as needed to understand the concepts involved. All homework assignments will be counted toward the final grade.
