Course Description: First and second order ordinary differential equations, the Laplace transform, and matrix systems of ordinary differential equations.
Prerequisites: MATH 2564 with a grade of C or better. Knowledge of the mathematical concepts learned in Calculus I and II, especially differentiation and integration techniques as applied to polynomial, exponential, and trigonometric functions.
Text: Differential Equations with BoundaryValue Problems, 9th Edition, by Dennis G. Zill.
Drill Sessions: Attendance in your drill section is required, and you must attend the section in which you are enrolled. Drill sessions are led by teaching assistant and meet once every week, including the first week.
Course grade: Here is how I plan to weigh your grades:
Homework  20% 
Midterm tests  15% each 
Final  35% 
Tests: There will be three midterms tests and a final exam. I plan to hold midterm exams during class time on the dates indicated in the calendar above. The final exam will occur in our regular classroom at the time indicated on the registrar’s website.
If you require accommodations on an exam, notify your instructor as soon as possible, but in all cases at least one week before the exam is to be held. Documentation from the CEA will be required.
Makeup exam requests also require written documentation as to your conflict. Except in the case of medical or other unforeseen emergencies, makeup exam requests must be made at least one week before the exam is to be held. Makeup exams are at the instructor's discretion; if you do not provide a documented reason why you cannot take the exam at the usual time, if your reason is considered inadequate, or if your request for a makeup exam is not made in a timely fashion, I reserve the right to refuse a makeup exam or to assess a late penalty (deduction from your score).
Homework: Assignments will be posted to this website. Each week you will be assigned a number of selfchecked problems and a smaller number of graded problems. You may ask anyone for help with your homework, but you must write up your solutions on your own.
Graded problems should be turned in for grading during class on the due date. We expect you to turn in your homework in class; if you cannot make it to class, either ask a classmate to turn in your homework for you or ask your instructor if they will accept homework at some other time. Late homework will not be accepted except in the case of a medical or other unforeseeable emergency; if you will be absent on the due date, consult with your instructor and arrange to turn homework in early.
Selfchecked problems will not be graded and need not be turned in. You will be able to check your answers by looking at the answers given in the back of the book. It is important that you do these problems; you will learn the material much better if you practice it by doing all problems, and material covered only on selfchecked problems and not on instructorcorrected problems will still appear on the midterm tests and final exam.
I expect to have 11 assignments over the course of the semester; your lowest score (or two scores) will be dropped.
Incompletes: Only given in extreme circumstances, and only when the student has satisfactorily completed all but a small portion of the work in the course. Students must make prior arrangements with the professor well before the end of the semester.
Academic Integrity: All students will be bound by and should familiarize themselves with the university's academic integrity policy.
