Instructor-corrected problems: (these problems should be turned in)
Do problems (AB 1), (AB 2), (AB 3) and (AB 4) in this file.

Homework is to be turned in in gradable condition. In particular:
  • Please write neatly.
  • Please write your name on your homework on the upper right-hand corner of the first page.
  • Please remove ragged edges due to tearing your homework out of a notebook.
  • If you have multiple pages to your homework, please attach the pages by stapling them in the upper left-hand corner. A paperclip or folding the pages over is not an acceptable substitute.
  • Please do not write in the upper left-hand corner of the pages (or upper right-hand corner, if you use the backs of pages) because I will not be able to see that region once your homework has been stapled.
  • Problems should be listed in the order in which they were assigned.
A student in this class requires a note-taker. If you are willing to upload your notes and plan to attend class on a REGULAR basis, please sign up via the CEA Online Services on the Center for Educational Access (CEA) website. On the CEA Online Services login screen, click on "Sign Up as a Note-taker". At the end of the semester you will receive verification of 50 community service hours OR a $50 gift card for providing class notes. All interested students are encouraged to sign up; preference may be given to volunteers seeking community service in an effort engage U of A students in community service opportunities. Please contact the Center for Educational Access at ceanotes@uark.edu if you have any questions.

If you are in Section 003 (regular lecture in PHYS 133 at 2:00), then your final exam will be 1:00–3:00 p.m.

If you are in Section 004 (regular lecture in CHEM 144 at 10:45), then your final exam will be 10:15 a.m.–12:15 p.m.

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 polynomials, exponential, and trigonometric functions.

Text: Elementary differential equations and boundary value problems, 10th Edition, by William E. Boyce and Richard C. DiPrima. I expect to cover chapters 1, 2, 3, 6, and 7.

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 a graduate assistant and meet twice every week, including the first week, depending upon your section number.

Course grade: Here is how I plan to weigh your grades:

Homework 20%
Midterm tests 15% each
Quizzes 5%
Final 30%

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.

Make-up exam requests also require written documentation as to your conflict. Except in the case of medical or other unforeseen emergencies, make-up exam requests must be made at least one week before the exam is to be held. Make-up 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 make-up exam is not made in a timely fashion, I reserve the right to refuse a make-up exam or to assess a late penalty (deduction from your score).

Quizzes: Quizzes will be administered during the Thursday drill sessions and will be graded on participation only. You will be allowed to work collaboratively on the quizzes. You may miss up to 2 quizzes without penalty. No make-up quizzes will be given.

Homework: Assignments will be posted to this website. Each week you will be assigned a number of self-checked problems and a smaller number of instructor-corrected problems. You may ask anyone for help with your homework, but you must write up your solutions on your own.

Instructor-corrected problems should be turned in for grading during drill 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 graduate assistant 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 graduate assistan and arrange to turn homework in early.

Self-checked 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 self-checked problems and not on instructor-corrected 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 and the remaining 10 (or 9) assignments will comprise 20% of your course grade.

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.
