Notes on the homework.

We will discuss some problems from the list given for each section in class. Note that the answer to odd-numbered exercises is given in the back of the textbook and in the Student Solutions Manual. After you have read the relevant section of the text, looked carefully at similar worked examples, and attempted a problem and got stuck, ask about it in class or in office hour!
