• Wednesday, Sep 8 A number of students have told me that they have a heavy class/lab schedule on Wednesdays and Thursdays, making it difficult to get the homework assigned on Wednesday completed by Friday. Therefore, I am changing the homework collection schedule so that each Friday, we will collect the problems assigned on the Monday of that week as well as those assigned on Wednesday and Friday of the previous week. This means that the homework due this Friday, Sep 10, will consist of:
  • Section 1.3 Problems 1, 2, 4, 5, 6, 8, 9, 15, 22
  • Section 2.1 Problems 5c, 6c, 14, 15, 22bc, 29a
  The problems from Section 2.3 are due on Sep 17.
  You can either turn in your homework in Friday's lecture, or put it in the APMA 0330 drop box in the lobby of 182 George St by 2:30pm on Friday. Please be sure to label all problems clearly (so that the graders can find them easily), staple pages together, and put your name on the top page.
