Course Description

This course is a survey of important types of differential equations, both linear and nonlinear. Topics include the study of systems of ordinary differential equations using eigenvectors and eigenvalues, numerical solutions of first and second order equations and of systems, and the solution of elementary partial differential equations using Fourier series.
Prerequisites: Math 13


Elementary Differential Equations and Boundary Value Problems (10th Edition) by Boyce & DiPrima, Wiley 2012


There will be two midterm exams and a cumulative final exam. The exams are scheduled as follows:

Exam 1 Tuesday, October 4, 4 - 6 pm Kemeny 008
Exam 2 Tuesday, October 25, 4:30 - 6:30 pm Kemeny 008
Final Exam Friday, November 18, 11:30 am Kemeny 008

If you have a conflict with one of the midterm exams because of a religious observance, scheduled extracurricular activity such as a game or performance [not practice], scheduled laboratory for another course, or similar commitment, please see your instructor as soon as possible. If you must miss a class, it is your responsibility to submit all homework on time.

Homework Policy 

Written homework assignments will be assigned weekly and will be posted on the daily schedule and homework pages. Homework will be due each Friday, a week from the day it is assigned, and is to be turned in to the homework boxes outside Kemeny 108. No late homework will be accepted. (Practice problems are not to be turned in, but you may be asked to present solutions in class.)

We have been assigned two graders for the course. Consequently, each homework assignment will be divided into two parts, Part A and Part B, as indicated on the daily schedule. In order to ensure consistency in grading, one grader will grade all problems in Part A, and the other, Part B.

Please separate your homework into an A portion and a B portion, staple each portion separately, and turn them in to the appropriate box outside Kemeny 108 on Friday by 3:30pm.

The Honor Principle

Academic integrity is at the core of our mission as mathematicians and educators, and we take it very seriously.

Cooperation on homework is permitted and encouraged, but if you work together, do not take any paper away with you; in other words, you can share your thoughts (say on a blackboard), but you have to walk away with only your understanding. In particular, you must write the solution up on your own. Please acknowledge any collaborators at the beginning of each assignment.

On exams, you may not give or receive help from anyone. Exams in this course are closed book, and no notes, calculators or other electronic devices are permitted.


Our graduate teaching assistant, Victor Churchill, will run tutorials Sunday, Tuesday, and Thursday at 7 - 9 pm in Kemeny 108, focusing on answering your questions as you work through the homework problems. Past students have found these tutorials to be immensely helpful!

Other Outside Help

  • Office Hours: Please feel free to meet with us during office hours (or by appointment) with questions regarding homework problems or any other aspect of the course.
  • Peer Tutoring: The Tutor Clearinghouse of the Academic Skills Center provides one-on-one peer tutoring.


The course grade will be based upon the scores on the midterm exam, homework, and the final exam as follows:

Written homework 15%
Exam 1 25%
Exam 2 25%
Final Exam 35%


Students with disabilities who will be taking this course and may need disability-related classroom accommodations are encouraged to make an appointment to see their instructor as soon as possible.
