- My office is 422 Carver, and the phone number there is
294-8136; I can also be reached via e-mail at email@example.com. E-mail is the easiest
way to contact me. My office hours
are 2-4 pm on Monday, 3-4 on Tuesday, and 10 am-12 noon on Wednesday. If
you can't make these office hours, either make an appointment or take your
chances. I'm usually also in my office between 2 and 4 every day and I
have another class (Math 166H) Monday, Tuesday, Thursday, and Friday
8-8:50 am. Click here for
modifications to my regular office hours.
- Be sure to purchase all appropriate course material for
the course from the bookstore. The textbook is Elementary Differential
Equations (sixth edition) by Edwards and Penney.
- The course will be graded based on three in-class exams
(September 17, October 15, and November 12) of 100 points each, one final
exam (time [tentatively scheduled for December 17, 7:30-9:30 am] and place
to be announced) of 150 points, and regular homework assignments worth 200
points total. Grades will be based on your total points out of 650
possible points. Approximate cut-offs are 90% (585 points) = A, 80% (520
points) = B, 70% (455 points) = C, 55% (357 points) = D. Adjustments to
this scale (such as plus/minus grades) will be made at the instructor's
- Grades will be posted on WebCT. You can access WebCT using your net-id
(which is the part of your university email address before the @) and
- Practice exams and solutions will be available a few
days before each exam. Here is practice exam #1.
Here is practice exam #2. Here is practice
- Here are the answers to practice
- Here is a practice final exam. Here are solutions
to problems #4 and #6 from the practice final exam.
- Solutions to exams will be available online a few days
after the exam.
- There is a syllabus at the bottom of this page. All of
the course material will be covered in the Final Exam.
- Homework assignments are on the web at www.public.iastate.edu/~lieb/266/hw.html.
Check this page regularly because there may be changes. There are
two kinds of homework problems listed. Problems labeled “to be handed in”
will be graded. Problems labeled "for discussion" should be
worked as extra practice if you need any. They will not be graded, but I
may use them as source problems for the exams.
- Make-up exams are available only in cases of emergency.
If you know ahead of time that you will miss an exam, see me to schedule a
make-up. Late homework assignments
will be graded when I have time, so your midterm grade may not include all

needing accommodations in this course, please make arrangements to meet
with me soon. Please request that a Disability Resources staff send a SAAR
