Professor David Groisser
If you would like to speak with me by phone or in person, please read the instructions on my schedule page before calling, emailing, or stopping by, and please do not call or stop by outside of my designated office hours and advising hours (unless we have previously agreed on an appointment outside those hours). My office is located in the 358 Little Hall area, and you must check in with the receptionist to see me. My phone number is 392-0281, extension 261, and my email address is groisser@math.ufl.edu

Office Hours: Tentatively 8th period Mon., Wed. and Fri. Please come early in the period or let me know to expect you later. See my schedule for updates. You can also see me by appointment any weekday except Thursday .

Text: Nagle, Saff, and Snider, Fundamentals of Differential Equations and Boundary Value Problems, 4th edition. We will cover chapters 1,2,4,6,7, and 8, with some omissions. Topics will include:

I discourage the use of solutions manuals. To learn mathematics, you need to see a small number of problems worked out, to illustrate the principles; you need to do a large number of problems by yourself.

Exams and Grading: Your final grade will be determined by the following

I reserve the right to adjust the percentages above in individual cases if I feel that circumstances warrant.

There will be no make-up midterms. If you have a valid, documented reason for missing a midterm, I will re-adjust the weights of your other exams.

See more about grading below for additional information.

Calculator Policy: Calculators are not allowed on exams, and generally should not be used for homework, although occasionally a homework problem may be assigned that requires a calculator.

Homework: will be assigned daily and is due by the next class, but will not be collected. It is critical that you keep up with the homework daily. Far too much homework will be assigned for you to catch up after a several-day lapse, even if you think from your past experience that you will be able to do this. Students who do not keep up with the homework frequently receive D's or worse (or drop the class to avoid receiving such a grade).

The assignments will be posted on the homework web page . The dates more than one day in advance are estimates and there will be frequent updates. Assignments may also be modified in class according to how far we get on a given day. You are responsible for checking this page frequently, since in addition to updated assignments, other important information such as exam dates will be confirmed on that page. Of course, changes of exam dates will also be announced in class well in advance, and more than once. However, if you are unaware of a changed exam date because you were not in class when it was and did not check the homework page for several days, and this causes you to miss an exam or do poorly on it, that grade (0 if you miss the exam) will still be averaged into your final grade according to the percentages above.

On most days I will not answer homework questions in class; you should see me in office hours for such questions. If we are making rapid enough progress, then occasionally I may set aside a day to go over homework. The class day before an exam will always be used for Q&A.

Workload: On average, in order to receive an average grade (C or C+), students with good preparation for this class should expect to spend two to three hours outside of class for every class meeting (6-9 hours per week). This time estimate is an average, not a maximum--some students will require more time, some less; some weeks the workload will be heavier, some lighter. Some circumstances that may increase your workload are:

Attendance policy. I expect students to be in class every day and on time, paying attention for all 50 minutes of the period. Coming late to class is disruptive both to your instructor and to your fellow students. If another time commitment (e.g. a class the previous period in a distant location) will force you to be late on a regular basis, you should not take this section of this class. There are 17 sections of MAP 2302 being offered, and one of them is bound not to conflict with your schedule.

Currently I plan to take attendance but not to factor it into your grade directly. However, students without good attendance should not expect the same consideration in office hours that students with good attendance will receive. Be aware that the University of Florida Attendance Policies contains the following paragraph:

The university recognizes the right of the individual professor to make attendance mandatory. After due warning, professors may prohibit further attendance and subsequently assign a failing grade for excessive absences.

More about exams. Most exam problems will be similar to homework, but on most exams I try to put at least one problem that you won't have seen a clone of before. Such problems will involve no new concepts , but may, for example, combine concepts from different parts of the syllabus. I do this to see whether you've gone beyond memorizing a bunch of formulas and rules, and have achieved a real understanding of the material--which you'll need for an A.

More about grading. I don't have a predetermined grade curve or predetermined percentages for letter grades. I decide the grade scale for each exam and homework according to the philosophy A = excellent, B = good, C = satisfactory, D = unsatisfactory but passing. At the end of the semester, I use the cutoffs from the exams and homework and to determine the final grade cutoffs on a 1000-point scale. For example if the cutoff for a B is 72% on the first hour exam, 69% on the second hour exam, 76% on the third hour exam, and 74% on the final, to get a B for the course you'd need .20 x (72%+69%+76%) + (.40 x 74%) = 73% of the total number of points in the course, i.e. 730/1000.

Since I don't determine the exam-grade cutoffs ahead of time, I can't tell you in advance exactly how many points you'll need to get a particular grade for the course. However, for an example of past grade scales, see the grade scale pages one and two and for the last time I taught this class (Fall 2002, two sections). There is no guarantee that this year's grade cutoffs will be close to those of the past classes ; they could be higher or lower.

Student Honor Code: Students are expected to abide by the the Honor Code:

We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.
On all work submitted for credit by students at the university, the following pledge is either required or implied: "On my honor, I have neither given nor received unauthorized aid in doing this assignment."

Religious Holidays: The following is part of the University of Florida Policy on Religious Holidays . "Students, upon prior notification of their instructors, shall be excused from class or other scheduled academic activity to observe a religious holy day of their faith."

Accommodations for students with disabilities: Students requesting classroom accommodation must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the instructor when requesting accommodation.
