Reminder: We've moved the next test to Monday, 11/19.
Homework 7.1-2 returned. Some of you did the problems off the
original assignment sheet I handed out the first day. That assignment
page is dynamic -- it changes! You must check the on-line version to make sure that you're up
to date.
For those who did the wrong problems, and submitted them, you may redo
the assignment for credit. This time!
