Prerequisites:
Math 1297 (Calculus II) or equivalent.
Student Conduct Code:
see the full description at www1.umn.edu/regents/policies/academic/Student_Conduct_Code.html.
Textbook:
Differential
Equations and Linear Algebra, 2nd or 3rd Edition, Edwards and Penney,
Prentice-Hall, is our primary textbook. It does not matter
which edition of the text you have.
Topics:
This course will build on your knowledge of
calculus, extending it to differential equations. In addition to their
intrinsic mathematical interest, differential equations are applied in a
wide variety of fields. In order to understand systems of linear
differential equations, we will also learn some basic linear algebra.
We will try to cover some sections from every chapter of the book,
although more attention will be given to chapters 1 through 7. These
will be covered at a pace of roughly one chapter per week.
Exams:
There will be two midterms (tentatively: February
28th and
March 28th) and a final exam. A
calculator and sheet of notes is allowed on each exam. For the final
you can use two pages of notes. The final exam will be held in EduE
50 from 2 to 4 pm, Monday, May 12th.
Practice exams:
Practice tests for the midterms and final will be posted here 1 week before the relevant exam.
Calculator Policy:
Calculators are allowed during exams
(note: an internet-capable device is not considered a calculator).
However, you are expected to show the steps that justify your answers,
and to give exact answers whenever possible. This also applies to
homework unless the question specifically instructs you to use a
computer or calculator. On a test, any step on which you use a
calculator must be clearly indicated (just write "CALCULATOR" or
"CALC").
Grading:
Grades will be based on your
understanding of the material as demonstrated by class participation
(mainly worksheets), office hours, homework, labs, and exams. The
homework assignments will be weighted equally, with the lowest score
dropped. The lowest lab score will also be dropped. The lowest three worksheet scores will be dropped.
The approximate weighting is homework is 20%, each
midterm 15%, labs 10%, worksheets 15%, and the final exam is 25%. Note
that I do not use traditional grading percentages, although generally
a score of around 90% of the total is sufficent for an A.
Worksheets:
Worksheets from class will be posted here.
Homework:
Late homework is not
accepted without a prior arrangement. Your answers should include intermediate steps - it is not
acceptable to only write down an answer.

Labs:
We will use the computer algebra system Sage
for our labs. Sage can be accessed through a browser at https://sage.d.umn.edu:8000/ or https://erdos.d.umn.edu:8000/
or Server 3.
Sage can also be used on a "cloud" version: https://cloud.sagemath.com..
It may be helpful to read this introduction, written by
professor Gregory Bard of UW Stout.

Interactive introduction to Python. This might be easier to use than the CodeAcademy site.
MIT ODE lectures online. This course is somewhat different from ours
but there is significant overlap.
Khan
Academy. These videos are 15 minutes or less and focus on one topic
at a time. Almost all of those in the "Differential Equations" section
are relevant to our course.
Code Academy's brief intro to Python. Totally optional but recommended.
