**Course Webpage: **http://www.westga.edu/~kshin/math3303

**Course Description:** This course
is an introduction to the subject of differential equations and has three
components:

- Existence theory and classical methods for first order equations (chapters 1&2)
- Real life applications and the theory of linear equations (chapters 3&4)
- Techniques and methods for solving general linear equations: operator method, power series, and an introduction to the Laplace transform (chapters 6&7).

We plan to use the computer algebra system Maple to explore topics such as the Laplace transform and the numerical integration of differential equations. If time permits, we will discuss some topics in Chap. 8.

**Learning Outcomes: **the
student will be able:

-To identify and classify a differential equation,

-To decide whether a solution is unique, and to find its domain of existence,

-To solve first order equations by classical methods,

-To model a simple process and determine its evolution for large time,

-To solve an inhomogeneous equation using undetermined coefficients or variation of parameters,

-To find power series solutions of linear equations with analytic coefficients,

-To use computer resources to solve ordinary differential
equations.

**Hour Exams:** Exam 1 (Wed, Sept 20), Exam 2 (Fri, Oct 20),

Exam 3 (Mon, Nov 20).

**Cumulative Final Exam:** Wednesday, December 6, 8:00
am - 10:00 am.

**Homework: **Homework
will be collected three times during the semester and will be posted at http://www.westga.edu/~kshin/math3303/.
It is due at the beginning of class on
Sep 15, Oct 16, and Nov 15. Each complete submission will receive 20
points and partial credit will be considered for incomplete work. However, late
submission will receive zero point.

**Quizzes: **There
will be a quiz on almost every Friday, consisting of one or two problems that
are identical or almost identical to homework problems. Each quiz will be 10
points and three lowest scores will be dropped. If needed, the total quiz score
will be converted to 140 point scale at the end of semester.

**Grade Scale: **3 Hour Exams 300 points (100 points each)

Final 200 points

Quizzes 140 points

Homework
60 points

----------------------------------------------------

Total 700 points

A: 630 - 700, B: 560 - 629, C: 490 - 559, D: 385 - 489, F: 0 Ð 384.

October 6 is the last day to withdraw the class with a grade of W.

**Attendance: **Attendance
is expected and required. You are responsible for all material covered in class
and all announcements made. Undetermined number of pop-up quizzes may be given
for extra points as a way of checking attendance. Such a quiz will consist of
one problem, discussed during the same class.

** **

**Make-up: **There
will be no make-up quiz. Make-up hour exams will be granted for official
University activities if the student notifies the instructor at least a week in
advance. There will be no make-up final except when a conflict with other
finals occurs. If a conflict occurs to you, please inform the instructor at
least two weeks in advance.

**Classroom Behavior:** You are expected not to disturb
your classmate's learning.

**Academic Honesty:** Academic honesty is fundamental
to the activities and principles of a university. All members of the academic
community must be confident that each person's work has been responsibly and
honorably acquired, developed and presented. Any effort to gain an advantage
not given to all students is dishonest whether or not the effort is successful.
The academic community regards academic dishonesty as an extremely serious
matter, with serious consequences.

In
this class, when it happens, the corresponding quiz or exam will receive 0
point and the person's final letter grade will be lowered by one level.
