Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to McCallum, Hughes-Hallett, et al., the required text for the course. You should write up solutions neatly to all problems, making sure to SHOW ALL YOUR WORK. A nonempty subset will be graded. You are strongly encouraged to work on these problems with other classmates, although the solutions you turn in should be your own work.

**Section 16.4**

Problems: 2, 3, 7, 12, 16, 17, 21

**Hint:** For problem #21, first write the volume as a triple integral in
the usual xyz-coordinates. Then do one integration to obtain a double integral.
Change this integral into polar coordinates to finish the problem.

**Section 16.5**

Problems: 2, 3, 7, 8, 21, 33
