Those of you who requested your finals back may find them outside my office. Happy holidays!
This is the main page for Math 307U, Introduction to Differential Equations. Here you may find the syllabus, homework assignments, exam dates, grading policies, and any other information pertaining to the course, as well as important announcements (such as room changes!). There is also a course mailing list, which I may need to use for last-minute announcements. As usual this mailing list will send you email at your @u.washington.edu address.
Lectures are Monday and Wednesday from 3:30 PM to 4:50 PM, in Room 003 of building EE1. Warning: this room is particularly difficult to find.
My office hours: 10:30-12:20 on Tuesday, in PDL C-8-K.
Here you may find current homework assignments with due dates.
Solutions to the first midterm are now available.
Solutions to the second midterm are now available.
My office is in the second basement of Padelford Hall, number C-8-K. You can also email me at rosoff@math.washington.edu.
The text for the course is Elementary Differential Equations and Boundary Value Problems, by Boyce and diPrima (8th edition). We will be covering chapters 2, 3, and 6 from this text. The material in these chapters pertains to first-order differential equations, linear second-order differential equations, and the Laplace transform, respectively.
Here is a page which has some instructions for using the software package Maple to plot direction fields and solve differential equations.
Here are some web applications for differential equations, provided by John Sylvester. These will draw direction fields and plot solutions of DEs for you.
Grades will be based on homework, the two midterm exams, and the final (dates of exams below). They will probably be given the following weights: proficiency test 5%, homework 20%, each midterm 20%, final 35%.
Here is the syllabus I handed out on the first day of class. You will need Adobe Acrobat Reader or equivalent software to view it.
Information on the proficiency test (date: Monday, October 11).
The midterm exams are scheduled for Wednesday, October 20 and Wednesday, November 17. I plan for the first midterm to cover Chapter 2 and for the second to cover Chapter 3, but as the reader has probably guessed this is subject to change. You will be permitted one standard size piece of paper with handwritten notes to assist your memory of the requisite formulae, but no calculators, computers, etc.
The final exam is tentatively scheduled for Thursday, December 16, 2:30 PM to 4:20 PM. This will be a comprehensive exam, but Chapter 6 will get just a bit more emphasis than Chapters 2 and 3 combined. If you find you have a conflict with any of these dates, please let me know as soon as possible.
