Text Book: W. Boyce and R. DiPrima, Elementary differential equations and boundary value problems, 9th ed., Wiley (2009). ISBN: 978-0-470-38334-6.

Coverage: Sections 2.1-2.6, 3.1-3.6, 5.2, 5.4, 5.5, 6.1-6.6, 7.1-7.6, 7.8, 10.1-10.5.

Lecture Homeworks:

Completing the assigned homework is vital to your understanding of the subject material. You should make every effort to complete the homework assignments and seek help with problems you have not been able to solve.

Optional WeBWorK assignments:

Additional homework problems and practice midterm exams will be available through the WeBWorK server at the Mathematics Department. More information will be available during the semester.


Students are expected to attend all class meetings and are responsible for all of the material covered in class. Any changes in this syllabus or in the scheduling of exams, WeBWorK, etc. will be announced during class meetings.

Course Grading:

Your course grade will be based on the maximum of the following two decompositions:

    • 14% HW/QZ (lowest dropped)
    • 14% Exam 1
    • 14% Exam 2
    • 14% Exam 3
    • 14% Exam 4
    • 30% Final Exam
    • 14% HW/QZ (lowest dropped)
    • 42% Best 3 of 4 Exams (14% each)
    • 44% Final Exam

In addition, you must take the final examination in order to pass the course. Since there are no makeup exams, if you miss an exam for any reason, your grade will be based on option 2.

Final grades will be assigned based on the following scale.

4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.0
[100, 90] (90, 85] (85, 80] (80, 75] (75, 70] (70, 65] (65, 60] Below 60

This scale may be curved to be more lenient, depending on the final grade distribution. However, such a curve is at the sole discretion of the instructor.
