There won't be any slides for the third lecture since most (all) the
material is from the book.  In tomorrow's lecture, we will potentially
cover the following: <p>

Figures: 3.13, 3.6, 3.8, 3.10 <br>

In-class exercises: 3.26, 3.20 <p>

Remember that code from the above figures is available at the class
home page: <p>

<p>

Please read chapter 3 and review the figures before coming to class. <p>

Here is the assignment for next week (due 9/16): <br>
Reading: Chapter 4 (4.1-4.6)  <br>
