## Old Announcements

• The course web site taught in Fall 2002, Fall 2001, and Fall 1999 contain old homeworks and mid-semester exams.
• I have put copies of the two textbooks (see syllabus) on reserve in the library. They will be available on Sep 3.
• Here is the Maple 7 (or 8,9) worksheet that demonstrates matrices. Note that you can load it by selecting "Maple text" and load it as Maple text. Then run it via edit->execute->worksheet. Lines that you type in are marked by "> ". The worksheet may be helpful in doing homework 2.
• Please remember that the exam is closed book/closed notes. But you can bring a single 8.5in by 11in sheet of paper with the key material on both sides.
• Since class was cancelled today, Thurs Sep 18, 2003 due to hurricane Isabel, the first mid-semester exam will be held in class on Thursday, Sep 25, 2003. Homework 2 will be returned in class on Tuesday, Sep 23, 2003. Then there will also be the pre-exam review, which was cancelled today.
