Do Lab 3.3 in the text. (This is on page 343.)

While this lab is purely analytic, requiring no numerical approximations to answer the questions, you may find MATLAB useful for producing illustrations for your report. Recall, however, the warning from Lab 2:
Note the authors' comment, `... although one good illustration may be worth 1000 words, 1000 illustrations are usually worth nothing.' If you feel tempted to include a large number of illustrations, analyze why, and see if you can say in words what you hope I would get from the illustrations. Then select a limited number of important examples.
