Exercise and HomeworkExercise problems will be assigned after each lecture. Students are expected to do the homework and participate in the discussions following the lectures.
TestsThere are three types of tests: Quizzes – quizzes will be given on a biweekly basis (drop one lowest). Midterm – Tentatively scheduled in the 7th week. Final exam – A comprehensive exam + an essay (project). Date and time check NMU Academic Calendar.
Final ProjectClose to the end of the semester, each student is required to write and present a formal essay on the applications of the ordinary differential equations to solving a real-world problem.

Class MaterialsLecture slides (including homework assignments) and Syllabus will be available through educat.nmu.edu. Slides normally will be uploaded near the end of a chapter.
Attendance and GradingAttendance will be checked randomly and will be calculated into the grade. Remember that the poor attendance is one of the primary causes of failing a class.Grades are calculated as a weighted average of the quizzes, midterm, final exam and the attendance. The weights are: Quizzes 50 % , Midterm 20 %, Final exam 25 %, Attendance 5 % Grading Convention: A 95%, A- 90%, B+ 85%, B 80%, B- 75%, C+ 70%, C 65%, C- 60%, D+ 55% etc.
ADA StatementsIf you have a need for disability-related accommodations or services, please inform the Coordinator of Disability Services in the Disability Services Office by: coming into the office at 2001 C. B. Hedgcock; calling 227-1700; or e-mailing disserv@nmu.edu . Reasonable and effective accommodations and services will be provided to students if requests are made in a timely manner, with appropriate documentation, in accordance with federal, state, and University guidelines.
What is a differential equation? - An equation involving functions and their derivatives. Example: The growth rate of a deer population is proportional to the population size at any time, namely, where P = population size, t = time, k = a constant. We would like to know how does the population change.
What is a differential equation?Another example, the rate of change of thetemperature of a cup of coffee is proportional to the difference of the temperature of the medium and the temperature of the coffee: where T = temperature of the coffee, Tm = temperature of the medium, t = time, k = a constant. We would like to know how is the temperature changing over time.
