Differential Equations, Math 2280, Spring 2008
Course Syllabus
Instructor: Dr. Seth Armstrong, ELC 402, cell number
590-4516 (the self-named Math Hotline),
email armstrong@suu.edu. Please relay information to me by email or
cell if possible. I do not check voice
mail on the office phone very frequently.
There will often be things posted on my web page at www.suu.edu/faculty/armstrong
like this syllabus, Mathematica
notebooks, and previous exams.
Meeting times and
Office hours: We
will meet T&Th,
11:30-12:50 in SC 230. Consultation in
my office is 2:30-3:30 daily. Please try
to make your visits during these times.
If my office hour is not possible for you to make I will be happy to
schedule another appointment. There is
also a tutoring lab in the
Prerequisite: Calculus II (Math 1220) and Linear Algebra (Math 2270), though the
latter may be a co-requisite with permission.
Text: Elementary
Differential Equations and Boundary Value Problems, 8th ed., by Boyce and DiPrima
Course Fee: The course fee is to cover graders as well as periodic updates of
math software such as Mathematica.
Catalog Entry (Poor): Linear and nonlinear differential equations and linear
systems of equations with applications; emphasizes understanding of the
solution as well as the techniques used.
(I would add Direction fields,
methods of solving first order equations, applications including computers,
linear higher-order equations and applications,
Policies and Procedures:
1.
Attendance
is required. I will be unwilling to go
through material that you miss without excuse.
You may drop your lowest test score (see #3) if you have two or fewer unexcused absences.
2.
Complete each homework (HW)
assignment the day it’s listed if your schedule allows. This will facilitate understanding of the
next day’s lecture. You should do your
HW as independently as possible. That
is, do all you can first on a problem
before seeking outside help. This is because the best way to learn
difficult material is to struggle through problems on your own. HW from the previous week’s material will be
collected each Tuesday. It may be handed
in any time up until 2:00, either in class or under my office door. It should be neat with the problems done in
order and it should show complete work to receive credit. Because you have a few-day interval between
the last HW assignment and handing it in, I will not give any time extension on
the HW unless you’ve been gone/sick with excused absence for the previous
week. Late unexcused HW will not be
accepted.
3.
There will be a short (25 minute, 50
point) mini-test every other Thursday
(more or less) that will be over material covered up to and including the
previous Tuesday’s lecture. Only six of
seven scores will count toward your grade if you have missed two or fewer days
without valid excuse. If you know you
will be absent for a mini-test, arrangements for a makeup must be made
beforehand: Please send me an email describing the situation and times that you
could make it up. If a last-minute
emergency arises, you must contact me as soon as possible to arrange a makeup
mini-test. Sleeping through an alarm, a
busy week, an appointment with a doctor or dentist (unless you’re sick) are not
legitimate excuses to reschedule a test.
4.
Scholastic
dishonesty will not be tolerated. HW plagiarism
(copying from a solutions manual or someone else’s HW) will
result in a zero on any assignment. Even
if you share methods and ideas in a group setting, the work that you hand in
should be entirely yours.
5.
Students
with medical, psychological, learning, or other
disabilities desiring academic adjustment, accommodations, or auxiliary aids
will need to contact the
6.
Grading The total will be 500 or 550 points, including 50 total from HW,
300 or 350 from the mini-tests (see #3), and 150 from the final exam. The grading scale will be the following. Please note that I will not raise a grade because of need; it is up to you to get the grade
you want.
