For those of you in my section, my office is 307 Bradley Hall and the telephone number is 646-1720. Other than coming to my office hours the best way to contact me is by email at guentner@cs.dartmouth.edu.

If you are in Prof. McAllister's section, his office is 411 Bradley Hall and his telephone number is 646-2960. You can go to his office hours, or contact him via blitzmail at Alex.McAllister@Dartmouth.edu.

Tutorials:

Tutorials for Math 23 will take place in 104 Gerry every Sunday, Tuesday and Thursday from 7:00 to 10:00 pm. These tutorials will be different from what you are accustomed to from your previous math courses in that there will be no graduate student tutor. Rather, they are intended to facilitate students in working on the homework problems together rather than individually. Occasionally, one of the instructors for the course, primarily John Finn, will drop in on the tutorial for an hour or two.

Exams:

As for scheduling, there will be two "hour examinations" and a final examination. The hour exams have been scheduled as follows:

Hour Exam 1	January 29, 1998	6:00-8:00 pm	Filene Auditorium
Hour Exam 2	February 19, 1998	6:00-8:00 pm	Filene Auditorium

If you have a scheduling conflict concerning the hour exams you should notify me before the end of the second week of the term so that arrangements for the exam can be made.

The Registrar's Office schedules the final exam, which will occur during the period March 13-17. If you must make travel plans before the schedule for final exams appears, Do Not make plans to leave Hanover before March 13. Exams Will Not be given early to accommodate travel plans.

Final Exam

March 14, 1998

Homework Policy:

Written homework will be assigned daily and will be due at 10am on the due date. The precise due date of each assignment will be indicated on the homework web page and will generically be the day of the next class meeting; this will eliminate confusion concerning use of the x-hour, etc.

Homework will be turned in and picked up from the boxes on the wall in the first floor of Bradley Hall, between 102 Bradley and Filene Auditorium (they are clearly marked for Math 23). Late papers will not be graded, and extensions will not be granted. Missing papers count zero. Moreover, neatness counts; if the grader can't read your paper, you get no credit.

Homework will be graded on an 0 - 2 point scale: 2, mostly correct; 1, about half correct, 0; mostly incorrect or missing. The three lowest homework scores will be dropped at the end of the term. The overall homework score will count 15% of the final grade in the course. Furthermore, there is a very strong correlation between those who do not do the homework regularly and those who receive low course grades.

Grades:

Homework	75 points	15%
Hour Exams	250 points (125 points each)	50% (25% each)
Final Exam	175 points	35%
Total Points	500 points	100%

The Honor Principle:

On Homework: Collaboration is permitted and encouraged, but No Copying. In other words, you should feel free to talk to other students while you are in the process of thinking about a problem. However, when it comes time to write up your solutions, you should do this by yourself without outside assistance.

Disabilities:

Differential Equations on the Web:

• A similar course was taught by Moses Glasner at Penn State. At his web site he has a direction field plotter. It works beautifully, and I urge you to check it out. This link was suggested by Mehmet Iyigun.
• We've encountered some tricky integrals already in Math 23. A student in John Finn's class suggested the integrator as an alternative to slogging through your old calculus book.
