Assignments:
1. Read Chapter 3 and use section reviews and practice problems to check your understanding.
2. Read over Note sheets (ns)*
3. Practice problems (p)*
4. Complete Graded problems (will announce due date in class)
5. Labs: TBA
* most note sheets and practice problems are separate and will be labeled either (ns) or (p) but on occasion some note sheets and practice sheets are combined. If so you will see (ns-p) at top of page.
