Professor Boris Botvinnik :
My office is 305 Fenton, and you can reach me by phone at 346-5636 or by e-mail botvinn@math.uoregon.edu . My office hours are at 1:00-1:50 pm on Mondays, Wednesdays or by appointment.

Lectures:
Monday, Tuesday, Wednesday, and Friday at 8:00-8:50 am in 306 Deady.

Textbook:
Elementary Differential Equations , Ninth Edition, by William Boyce and Richard DiPrima. Students will be expected to read the textbook carefully, and will be responsible for all the material in those sections that are covered in class. The text contains answers to all problems.

Prerequisites:
Math 251, 252, 253 or instructor's consent.

Course Content:
Math 256 covers basic theory of differential equations. Students are expected not only to learn how to solve particular differetial equations anlytically and somtimes numerically, but also to understand the basic abstract theory of differential equations (existence, uniquence and stability).

Homework:
Homework is due in class on Wednesdays, beginning October 7. Late homework will not be accepted. There will be 9 homework assignments, the last of which will not be graded. Your lowest homework score will be dropped. You may collaborate with other class members on your homework, although you must each write up your solutions independently and in your own words. To avoid falling behind, you should do the reading and homework as the material is presented in class, rather than leaving it all until the last minute.

Exams:
There will be two midterm exams, given in class on Fridays, October 23 and November 20. If you are forced to miss a midterm due to extraordinary circumstances, you must get my permission and schedule a make-up exam in advance. The final exam is scheduled for Monday, December 7 at 10:15 am - 12:15 pm.

Grading:

Homework:	20%
First Midterm Exam:	20%
Second Midterm Exam:	20%
Final Exam:	40%
