Grading policy: Final grades will be determined on the basis of the total numerical score (0-500 points) achieved on exams. Relative weights are:

 Final: 150 pts (30% of grade) Hourly Exam 1: 100 pts (20% of grade) Hourly Exam 2: 100 pts (20% of grade) Hourly Exam 3: 100 pts (20% of grade) Weekly Quizzes: 50 pts (10% of grade) Total: 500 pts (100% of grade)

Additionally, I will randomly and frequently ask students to do problems at the board.

• Final exam: 1:30--4:30 P.M., Wednesday, May 13.
• Hourly exams: Friday February 13, Friday March 13, and Monday April 27. These exams will be given in class.
• There will be 7 surprise quizzes, each worth 10 points. The two lowest scores on these quizzes will be dropped.

Outline: The first part of the course will be dedicated to an understanding of the definition of ODE's and quantitative propertices of some simple ODE's. Then we will discuss linear ODE's in some detail. We will then spend a short amount of time convincing ourselves of the ``abstract'' statement that ODE's have unique solutions. Then we will further discuss the quantitative properties of nonlinear ODE's and end with some numerical considerations.
