Text: Elementary Differential Equations with Boundary Value Problems, second edition, by W. Kohler and L. Johnson

Prerequisites: Math 2114 or 1114 and Math 1226 or 1206

Course Content: In this course you will learn to solve ordinary differential equations and get an understanding of the underlying theory. The topics include first-order equations, second- and higher-order linear equations, linear systems, and numerical methods. You will see that the solution methods are useful in a wide variety of applications.

Tests/ Quizzes/ Final Exam: Your grade will be based on homework, quizzes, three in-class exams, and the final exam. The exams dates are:

Exam 1: Thursday, September 28

Exam 2: Thursday, October 19

Exam 3: Thursday, November 30

Final Exam: Friday, December 15, 7:00-8:00 pm (common time part only)

Quizzes will be announced and will usually be given on Thursday and the questions will be based on the latest homework (if it was turned in on Tuesday).

Evaluation Policy: The three in-class exams each count for 20% of your grade. The quizzes together are worth 20% and the homework is worth 10% of the total grade. The final exam counts for 10% of your grade.

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

Final exam: The final exam will be a cumulative multiple-choice exam. The final exam time is a required class meeting that will not be rescheduled for discretionary reasons, including conflicts with work schedules or with classes or exams at other colleges, and travel plans. Students with three final exams within 24 hours should reschedule a non-common final exam.

Homework: Homework will be assigned on a regular basis and must be turned in on some due date at the beginning of class (usually this will be on Tuesday). The homework assignments will be posted on Canvas. The homework will be graded, but sometimes only selectively and/or for completeness. You are allowed to discuss the problems with me and/or other students while you are working on them. However, the work you turn in must represent your understanding of the material and it must be written up independently. Late homework will only be accepted in special circumstances upon consultation with me.

Absences: Make-up exams will generally not be given. If a student has a valid excuse (e.g. documented illness) the student should contact me before the exam.

Attendance: Attendance will be taken for Mathematics Department records. Attendance does not affect the computation of your grade.

Virginia Tech Honor System: I will assume that you have read the Va Tech Honor policy ( and I expect you to abide by it. The Undergraduate Honor Code pledge that each member of the university community agrees to abide by states: "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." 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.
