Johanna Franklin will be teaching this course.


The textbook is Differential Equations by Paul Blanchard, Robert L. Devaney, and Glen R. Hall (fourth edition), but it's all right to use the third edition instead. Used copies of the third edition should be available in the UConn bookstore as well as the fourth edition. Please let me know if you're having trouble finding the book.


The course grade will be determined as follows:


Homework will be assigned weekly but not collected. The purpose of homework is for you to understand the concepts taught in class and to be able to solve problems on your own, and it is very difficult to succeed in this course without doing the homework!

If you aren't convinced yet, consider this analogy: trying to take a quiz or exam without doing the homework on the concepts tested on it would be like trying to play basketball after just watching tape of other games.

You're certainly allowed to talk about the problems with your classmates and ask me questions if you get stuck, though copying your classmates' solutions is not allowed and will be considered to be a violation of the UConn academic integrity policy. You must write down the names of any classmates you work with on your homework assignments. You are allowed to use any kind of calculator you like when you do the homework, but I urge you not to rely on it heavily since you will be required to show your work on all quizzes and exams to get credit.


Ten-minute quizzes will be given on most Tuesdays when exams are not (see the schedule). You will be allowed to use your solutions to your homework assignments for assistance, but they must be obviously your solutions (the easiest way to ensure this is to write them in your handwriting). You will have to turn them in with your quiz paper and include the names of the other students you worked with. Of course, you are also welcome to attempt this without your homework solutions, but I warn you that it might not be very easy.

No makeup quizzes will be given, but the lowest quiz score will be dropped.


There will be two midterms and a comprehensive final exam in this class. The midterms will be given in class on September 25 and October 23. Please avoid making travel arrangements that would not allow you to take the final at the scheduled time (I'll post the date here as soon as I know what it is). UConn policy is not to allow rescheduling for this sort of reason. OSSA requires students who have a conflict about which they have or should have had advance notice to seek permission to reschedule their exam no later than November 30th. Please note that vacations, previously purchased tickets or reservations, graduations, social events, misreading the assessment schedule, and oversleeping are not viable excuses for missing a final exam. If you think that your situation warrants permission to reschedule, please contact OSSA to meet with a staff member.

I apply almost the same policy to midterm exams as the final exam: if your reason for missing the midterm would be acceptable as a reason for missing the final, I will arrange for a makeup exam, but not otherwise. The exception is the "Bunched Finals" clause on that page -- I won't reschedule your midterm in a situation like that.

You are welcome to bring a calculator to your midterms and your final exam as long as that calculator satisfies the Mathematics Department Calculator Policy (reproduced below). If you aren't sure whether your calculator is acceptable, please come see me before the exam.

Calculators that can perform symbolic operations (such as the HP 28 or 48, or TI-92 or 89) are not allowed. If you bring a calculator to the exam, make sure it cannot perform alphanumeric manipulation. The instructor may randomly ask for calculators and check programs stored in memory. No alphanumeric formulas stored as programs are allowable. Discovery of such material will result in serious consequences. Sanctions can include, but are not limited to, a letter sent to the Dean of Students of the University; a grade of 0 on the assignment, quiz or exam; a grade of F for the course.

You should know that I will never assign a problem on an exam that will require the use of a calculator and that overreliance on your calculator may actually hurt you!


If you're having trouble understanding the course material, you have a few options...

Academic Integrity

I expect you to be familiar with and abide by UConn's academic integrity policy at all times. There should be no help given or received on quizzes, midterms, or the final exam, and you will not be allowed to use computational aids that do not satisfy the calculator policy described above in the Exams section (note that slide rules and abaci are acceptable).

Accessibility Issues

If you have accessibility issues, I encourage you to discuss possible accommodations with me and consult the Center for Students with Disabilities in Room 204 of the Wilbur Cross Building. This office can help determine appropriate accommodations for you.

Religious observances

Some students may wish to take part in religious observances during this academic term. If you have a religious observance that conflicts with your participation in the course, please meet with me before the end of the second week of the term to discuss appropriate accommodations.
