** Student Conduct Code:**

**Textbook: **

Differential
Equations and Linear Algebra, 2nd or 3rd Edition, Edwards and Penney,
Prentice-Hall, is our primary textbook.

**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 chapters 1 through 7, and chapter 10. These
will be covered at a pace of roughly one chapter per week. If time
permits we might also cover portions of chapter 9 (nonlinear systems)
and/or chapter 11 (series solutions).

**Exams: **

The midterm exam will be on Wednesday, July 3rd. A
calculator and sheet of notes is allowed on each exam. For the final
you can use two pages of notes.

**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. Grades will be
assigned on a curve. The lowest two worksheet scores will be dropped.
The approximate weighting is homework is 20%,
midterm 20%, labs 10%, worksheets 15%, and the final exam is 35%.

**Worksheets**:

**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.

Assignment 1 (due Monday, June 17th).

Assignment 2 (due Tuesday, June 25th).

Assignment 3 (due Tuesday, July 2nd).

Assignment 4 (due Thursday, July 11).

Assignment 5 (due Thursday, July 18).

Assignment 6 (due Thursday, July 25).

Assignment 7 (due Thursday, August 1st).

**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://rigel.d.umn.edu:8000/ or https://rudolph.d.umn.edu:8000/. You can access those off campus if you are on a VPN connection (see this for how to get on a VPN). If for some reason the server is down, you can also use the worldwide accessible server here although you would have to upload your previous work to it.

Help on Sage: The first two sections of the 'constructions' document (available live from the 'Help' link on a worksheet, or statically here) are especially useful for this course, as are the first few sections of the reference manual. There is also a quick reference sheet that may be helpful. Sage is based on the popular programming language Python; if you want a better understanding of python a good place to start is its official tutorial. A variety of other documentation is available here.

Lab 1 (due 6/21) online published Sage version on sage.d.umn.edu server , online published Sage version on rigel.d.umn.edu server, online published Sage version on rudolph.d.umn.edu server.

Lab 2 (due 6/28) online published Sage version on sage.d.umn.edu server , online published Sage version on rigel.d.umn.edu server, online published Sage version on rudolph.d.umn.edu server.

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.

Code Academy's brief intro to Python. Totally optional but recommended.
