Fall 2007

Department of Mathematics

SUNY at Stony Brook

Differential equations are the language in which the laws of physics are expressed. This course will introduce basic methods for solving ordinary differential equations. There is a particular emphasis on linear differential equations with constant coefficients and systems of differential equations. Numerous applications in the physical, biological, and social sciences will be discussed.

**Homework:** Working homework problems is the only way to really learn the material. While you are encouraged to work with others, you must write up all solutions on your own. Homework sets will usually be collected in class on Fridays. No late homework will be accepted, but the lowest homework grade will be dropped. If you miss a homework assignment, you should still work out the problems on your own. Also, you are encouraged to read the corresponding section of the text book *before* attending each lecture.

**Exams:**

- Midterm 1: Wednesday, October 10 (in class). Review Sheet, Review Sheet Answers, Midterm 1 Solutions
- Midterm 2: Wednesday, November 14 (in class). Review Sheet (Answers). Midterm 2 Solutions
- Final Exam: Monday, December 17, 2-4:30p (in classroom Harriman 116). Review (Answers)
- Final Exam Review with Stimpson: Sunday Dec. 16 3p Library N3063

**Class schedule:**

LEC 1 | MWF | 11:45am-12:40pm | Harriman Hall | 116 | Corbett Redden |

R01 | Tu | 9:50am-10:45am | Physics | P117 | Andrew Stimpson |

**Textbook:**: *Differential Equations and Boundary Value
Problems: Computing and Modeling* (4th Edition), by Edwards & Penney.
Pearson/Prentice Hall, 2008. Though we use the 4th edition, it appears that the homework problems are identical to the 3rd edition.

**Prerequisites: **The completion of one of the standard calculus
sequences
(MAT 125-127, MAT 131-132, or MAT 141-142) with the grade C or higher
in
MAT 127 or 132 or 142 or AMS 161. The course will rely *heavily*
on material covered in the standard calculus sequences.
Familiarity with complex numbers and the basic
concepts of linear algebra will be important, so the 200-level courses
MAT 203/205 (Calculus III) and/or AMS 261/MAT 211 (Linear Algebra) are strongly recommended.

**Course Grade:** Midterm 1 25%, Midterm 2 25%, Final Exam 35%, Homework 15%

**MLC:** The Math Learning Center is located in Math Tower S-240A and offers free help to any student requesting it. It also provides a locale for students wishing to form study groups.

**Disabilities:** If you have a physical, psychological, medical
or learning disability that
may impact your course work, please contact Disability Support Services, ECC (Educational Communications Center) Building, room 128, (631)
632-6748. They will determine with you what accommodations are necessary and
appropriate. All information and documentation is confidential.
