Textbook: Elementary Differential Equations, by W. Kohler and L. Johnson, Addison Wesley, 2nd ed. 2006.

Course Content: Chapters 1-4 and 6. Topics include:

Prerequisites: Math 2114 or 1114 and Math 1226 or 1206.


The final grades are based on the following work:

A 90% will guarantee an A-, 80% a B-, 70% a C-, and a 60% a D-.

Homework: Weekly homework assignments are due on Tuesday before class starts. A few randomly selected problems will be checked each week. Each of the checked problems will contribute equally to that week's homework grade. The rest of the problems will not be marked, but you are encouraged to compare your answers with solutions that will be posted online. Homework sheets and solutions will be published on canvas. 

Quizes: There will be one graded quiz each week starting Thursday, September 14. Graded quizzes are taken online, and will be accessible from Thursday until Wednesday the following week. You must start a graded quiz by 11 pm on the day of the deadline. Each quiz will have ten questions from a database of practice quizzes. The questions are chosen randomly from the database, so different students will have different questions.

  • Click here to see a table listing how practice quizzes correspond to sections in the text.

You log in to the practice quiz system with your Virginia Tech PID and Password, and log off when you are finished practicing. This server has no connection to the testing server, which means that you will not risk losing any graded work if you forget to quit your browser. It also means that these practice problems will not be available when you view past tests. If you want to review your practice quiz problems later, you can mark up to 30 individual problems using the link below each graded practice problem. There is a link to your list of marked problems available anytime you are in the practice problem system.

The following is a list of graded quizzes and their deadlines. All quizzes are cumulative. The practice quizzes covered in each quiz will be added as the date of the quiz approaches:

  • Quiz 1: 9/20
  • Quiz 2: 9/27
  • Quiz 3: 10/4
  • Quiz 4: 10/11
  • Quiz 5: 10/18
  • Quiz 6: 10/25
  • Quiz 7: 11/1
  • Quiz 8: 11/8
  • Quiz 9: 11/15
  • Quiz 10: 11/29

  • Midterm 2: Thursday, Nov. 2

Midterms are cumulative. Above dates are tentative.

Final Exam Schedule: Friday, December 15, 7:00 pm - 9:00 pm. The final exam is a required class meeting that will not be rescheduled for discretionary reasons, including conflicts with work schedules, conflicts with classes and exams at other colleges, and travel plans.


Missed Assignments: There will be no make-up homework or quizzes. To account for potential missed assignments, the two lowest grades from both homework and quizzes will be dropped for all students.

Late Assignments: No late assignments. Assignments submitted past the deadline will be considered as missed assignments. 

Missed Exam: Missed exams will be dealt with on individual basis. A valid reason for missing an exam has to be provided.  

Grading Appeals: Specific grading disputes should be brought to my attention within 1 week of return of the graded assignment. Appeals outside of this timeframe will not be considered.

Honor Policy: All assignments and tests submitted will be considered graded work and must be completed individually.  No consultation is permitted on tests and quizzes. Homework may be discussed with other students as well as with the instructor. However, in writing up an assignment to be handed in, each student works alone and certifies that what is written accurately represents the student’s own understanding of the material expressed in the student’s own words. It is permitted to consult someone else's work when working on a homework assignment, but in such situations students are required to acknowledge using the source in writing (e.g. "I consulted Barbara's solution"). 

The Undergraduate Honor Code pledge that each member of the university community agrees to abide by the following:

“As a Hokie, I will conduct myself with honor and integrity at all times. I will not lie, cheat, or steal, nor will I accept the actions of those who do.”

The Virginia Tech honor code pledge for assignments states:

I have neither given nor received unauthorized assistance on this assignment.

The pledge is to be written out on all graded assignments at the university and signed by the student. The honor pledge represents both an expression of the student's support of the honor code and an unambiguous acknowledgment that the student has, on the assignment in question, abided by the obligation that the Honor Code entails. In the absence of a written honor pledge, the Honor Code still applies to an assignment.

Students enrolled in this course are responsible for abiding by the Honor Code. A student who has doubts about how the Honor Code applies to any assignment is responsible for obtaining specific guidance from the course instructor before submitting the assignment for evaluation. Ignorance of the rules does not exclude any member of the University community from the requirements and expectations of the Honor Code.

Disability Statement: If you need adaptations or accommodations because of a documented disability, if you have emergency medical information to share with me, or if you need special arrangements in case the building must be evacuated, please make an appointment with me as soon as possible.

Enrolment: It is the student's responsibility to be enrolled in the correct section. No changes in the class roll can be made after the last 'add' date. Please do not approach me with enrolment requests, I do not have rights to process them.
