Elementary Differential Equations withs Boundary Value Problems,
2nd Edition.
Synopsis
First order ordinary differential equations and linear systems. Brief introduction to
nonlinear dynamics in 2d and qualitative behavior. Fourier series, partial differential equations,
boundary value problems and Sturm-Liouville theory.
Course Objectives
This course will introduce the classical theory of differential
equations. We will begin with the fundamentals of ordinary differential equations
and then build on this theory to solve some partial differential equations. While we
will learn the mechanics of computing solutions, the primary goal of the course is to
develop a way of thinking and an understanding of the rich structure that underlies
the methods.
Prerequisites
A solid understanding of fundamentals from linear
algebra is essential. This includes the concepts of linearity, span, basis, eigenvalues
and eigenvectors as well as the ability to use them in argument and calculation. We
will also make frequent use of single-variable and multi-variable calculus as covered
in Math 212. It will be beneficial to review this material on your own; some key
concepts will be briefly reviewed in class/homework.
Grading
Your grade will consist of the following components:
- Weekly homework (15%), lowest dropped
- Midterm exams (20% each)
- Final exam (45%)
Important note: Your final grade will be based on a complete evaluation of
your performance in the course, which includes some instructor discretion. The
percentages listed are intended to give you a sense of the relative importance of each
component; consider the computed value to be a baseline and not a formula for
computing your grade.
Homework
- Homework will be assigned weekly, except before midterms and the final
exam. Due dates will be listed on Sakai; typically one week after assigned.
- No late homework will be accepted,
barring exceptional circumstances as per Duke policy. The lowest homework score will be dropped.
- Working and studying in groups is encouraged
(you will get much more out of doing homework if you discuss it with others!).
However, you should write your own solutions to each problem in your own words.
- Solutions should be complete arguments; the process by which you
arrive at the solution is far more important than a correct answer.
- Solutions should be clearly readable and in the order of the assigned problems.
Ethics
Students are expected to follow the Duke Community Standard.
If a student is found responsible for academic dishonesty
through the Office of Student Conduct, the student will receive a
core of zero for that assignment. If a student’s admitted academic
shonesty is resolved directly through a faculty-student resolution
agreement approved by the Office of Student Conduct, the terms of that
ent will dictate the grading response to the assignment at issue.
