**Text**:
*Differential Equations and
Linear Algebra,* Second Edition, by Stephen W. Goode.

We will cover (portions of) Chapters 1-9, and may cover some material not
included in the text if time permits.

**Catalog Description**: Introduction to
first order differential equations, linear differential equations with
constant coefficients, and systems of differential equations; vector
spaces, linear transformations, matrices, determinants, linear dependence,
bases, systems of equations, eigenvalues, eigenvectors, Laplace transforms,
and Fourier series.

**
Homework**: I will assign homework
problems essentially every class. Homework will not be collected. Homework
assignments will be announced in class, posted on my web page, and
occasionally discussed in class as necessary.

**
Quizzes**: There will a number of short
(approximately 10 minute) quizzes in class throughout the semester. Quiz
problems will be similar to the problems you encounter in the homework.
There will be no make-up quizzes, but your lowest quiz score will be
dropped. In total, the quizzes will be worth 100 points.

**
Exams**: There will be four hour-long,
in-class exams, each worth 100 points. These exams will tentatively take
place during the weeks of September 4, September 25, October 16, and
November 6. Exam dates will be announced in class. No make-up exams,
except in extreme cases. If you must miss an exam, you should notify me
before the exam takes place.

**Final**:
There will be a comprehensive final exam worth 200 points.

For Section 3, the final exam is scheduled for Saturday, December 9,
10:00 am - 12:00 noon.

For Section 4, the final exam is scheduled for Friday, December 8,
12:30 - 2:30 pm.

**Grade**:
Your course grade will be out
of the 700 possible points outlined above. I typically curve course
grades. However, 90-100% is assured an A, 80-89% a B, and so on.

**Important Dates**:

August 28 |
September 4 |

August 30 |
October 5-6 |

November 5 |
November 23-24 |

**Notes**: As the titles of the course and
text indicate, our objective is to introduce differential equations and
linear algebra. These two subjects are tools you will undoubtably
encounter and have occasion to use as you progress through your science
and/or engineering courses. We will develop methods for solving (certain
classes of) differential equations and problems in linear algebra. We will
also endeavor to develop an understanding of why these methods work. To
this end, we will work with objects known as vector spaces. The ideas we
develop will, among other things, provide us with a means of understanding
the theory underlying the solution of linear differential equations. There
is, however, no such thing as a free lunch. The level of abstraction in,
for instance, chapters 5 and 6 will probably be somewhat higher than what
you've encountered in prior courses.

In general, to stay on top of the material, it is important that you attend class, read the text, and do the homework regularly.

Bear in mind that you are taking this course under the guidelines of the Code of Student Conduct.
