Elementary Differential Equations  Math 242 - Section 4, Fall 2002
Text:   A First Course in Differential Equations with Modeling Applications , Seventh edition, by Dennis G. Zill.  BROOKS/COLE, 2001.   General topics from Chapters 1-5, 7, and 9.

Meeting times: TTh 2:00 - 3:15 PM at 405 LeConte .

Exams: There will be three 1-hour exams announced well in advance of their date (tentative dates Sept. 17, Oct. 24, Nov. 19). Each exam will be worth 100 points.  There will be no makeup exams.

Final exam: There will be a final exam worth 200 points on Wednesday, December 11 at 2 PM. All students must take the Final Exam.

Quizzes: There will be a ten-minute quiz almost every week. Three or four of the quizzes will be take-home ones, and will be based on Maple assignments. Each quiz will be worth 10 points. There will be a total of about 12 quizzes. Your best 10 scores will be chosen to constitute a quiz grade of a possible 100 points. There will be no makeup quizzes. Any missed quiz will be the one that you drop.

Maple: The topics of Modeling (Chapters 3 and 5) and Numerical Solutions (Chapter 9) will be connected with the use of the expert system computational algebra package Maple. Part of the classes that consider these topics will be held at LeConte 303 A. Tentative periods for these classes are Sept. 19-26, and Nov. 21 - Dec.3. Some Maple-worksheets and lessons can be found here.

Homework: There will be homework problems assigned but not graded. Quizzes will be based on homework problems.

Grading: You have a total of 600 possible points: 100 points for each of the three 1-hour exams, 100 points for the quiz, and 200 points for the Final Exam. You will be able to drop the lowest 100 points. The lowest 100 points may be one half of the Final Exam. This gives you a possibility of 500 points.
Your final grade will be determined from these 500 points as follows:
450-500: A         430-449: B+         400-429: B         380-399: C+         350-379: C
330-349: D+       300-329: D           000-299: F

ADA: If you have special needs as addressed by the Americans with Disabilities Act and need any assistance please notify the instructor immediately.

Attendance: Regular class attendance is important. Consistent with the USC Undergraduate Bulletin, a grade penalty may be applied to any student missing more than five classes (10%) during the semester.
