Topics
- Review (Section 11.1):
Curves in 2 and 3 dimensions, smooth curves,
parameterizations, arc length

- Line integrals of vector fields, work
- Mass and center of mass of wire
Read
Section 14.2. Skim over the formal definitions and theorems,
focus on the "evaluation theorems".
You can skip the last example (Ex. 2.9).
Homework
Section 14.2:
1, 7, 9, 21, 25, 27, 43, 45, 47. (For 45 and 47 just set up the integrals
as ordinary one-variable integrals with respect to the parameter t.)
