Textbook
A second course in Elementary Differential Equations, by Paul Waltman, Dover 2004
Topics to be covered:
1. Systems of Linear Differential Equations (Ch. 1  45 weeks)
2. Two dimensional autonomous systems (Ch. 2  45 weeks)
3. Existence Theory (Ch. 3  3 weeks)
4. Boundary Value Problems (Ch. 4  2 week)
The schedule is tentative, and time periods are approximate.
Homework
There will be homework assignments due about every two weeks, usually on Thursday.
No late homework will be
accepted. However, the lowest homework score will be dropped.
Each homework assignment will include a number of starred problems that will count for the 643 level course credits.
Important: it is your responsibility to show your work and to
present it in readable form. Answers without justification will
receive no credit.
You must do the homework regularly. Doing and understanding the homework is extremely important in this class.
They can be challanging, so I advise you not to wait
until the last minute!
Exams
There will be 1 midterm exam and a takehome final exam:
 Midterm exam: Oct 16, 2012 (tentative)
 Final exam: due by Dec 14, 2012
The midterm exam will take place in the classroom during regular class time.
The exam must be taken on the scheduled date. There will be no makeup exam, unless extenuating circumstances exist and arrangements have been made prior to the exam.
For the
643 level course, students will also be requested to work on a project, whose topic will be agreed upon with the instructor during the semester, and do a related presentation before the end of the semester.
Grade
Your course grade will be determined by your score in the exams (75%) and homework (25%).
For the
643 level course, your grade will be determined by your score in the exams (50%), project (25%), and homework (25%).

Disability services
Students with disabilities should notify me as soon as possible of any special needs. They should also provide me with their letters of certification from the Office of Disabilities (Main Hall 105, phone: 2553354) within the first two weeks of class.
A word of caution
This course turns out to be very difficult.
To do well, you should:
 Review background material;
 Study regularly;
 Read ahead each topic before class;
 Come to *every* class and ask questions;
 Review the material afterwards, stressing the understanding of concepts;
 Do the homework regularly;
 Seek help (from me or your SI or your classmates) when you don't understand something.
You are welcome (in fact, encouraged) to review with others and help each other.
Note however that everything you turn in should be your own work.
