Announcements
To be successful in this class, you are expected
to attend every class and stick around after class to ask questions
(which will take the place of office hours). You are expected to learn
all of the material in the sections of the book which have HW problems
assigned, mostly by completing the HW. While students are encouraged to
help each other with the HW, for example by giving each other hints,
purely copying HW solutions is not allowed. Make sure you master the
material covered by the HW problems since it will show up on the
midterms and the final exam.
Your homework for the semester is
listed below.
Homework will typically be due on Tuesdays and Fridays by midnight, unless otherwise stated.
Class meets weekdays from June 27 to August 4, except for July 4.
The two midterm exams are on Friday, July 15,
and Friday, July 29.
The final exam
is on Sunday, August 7,
from 2 - 5 pm in our usual classroom.
NOTIFY HUBERT BRAY (bray@math.duke.edu) IMMEDIATELY if you have any conflicts with these exam dates.

Homework #5 (due on Friday, July 15, 2022) MIDTERM 1 on this date in class.
Create a one page, front and back, review sheet which you may use
during the midterm exam which we take on this date. Turn in your review
sheet and the exam at the end of class.
1. The review sheet must be written by you in your handwriting.
2. The review sheet must be a physical (not digital) standard 8.5 x 11 inch piece of paper.
3. The review sheet must be created with a pen or pencil by you - no printouts or photocopies, even of your own handwriting.
4. While you should not just copy someone else's review sheet, after
making most of your review sheet on your own, you are encouraged to
compare your review sheet with other students for ideas about how to
make your review sheet better. The goal is to maximize learning for
everyone.
5. Make sure you include Table 6.2.1 in section 6.2 on your review sheet.
By writing small, you can get a great deal of information on your
review sheet. The process of deciding what goes on your review sheet,
as well as the process of actually transcribing it to your review sheet
with a regular pen or pencil is very educational for you. These are the
reasons for the above rules.
Make sure you take and study the practice exams at the top of this page to prepare for the exam as well. Good luck!
