**Inst: B. Walsh --- Hill Center 728
(Busch) --- (732) 445-3733**

This syllabus is subject to change. A current version will always be available from the Section Home Page.

**IMPORTANT: the list of problems is adjusted
throughout the semester.** *You are responsible for all assigned
problems; quizzes will be based on these assigned problems. Make sure that
you understand the solutions to all of them!*

There will be **Additional notes** on the following subjects:

Some of these notes contain homework problems, which are indicated as "N1", etc, in the syllabus. These are also available from the main 252 web site. To visit it (with notes, applets, and all sorts of good stuff) click here: Math 252 WebPage.
