TEXT: Elementary Differential Equations and Boundary Value Problems, W. Kohler and L. Johnson, Pearson/Addison Wesley Publishing Company, 2004.


COURSE CONTENT: Selected topics from Chapters 1 6 and Chapter 9.


OBJECTIVES: The objective of this course is to develop an understanding of the concepts presented in the textbook assignments and the lectures, and to apply these concepts to problems in science and engineering.


GRADING CRITERIA and EVALUATION PROCEDURES: At least two and no more than three "one hour" exams will be given. These exams will be closed book, in-class and will be announced at least one week in advance. Homework will be assigned and randomly selected problems will be graded. I plan to use the WeBWork system for some of the homework. In addition, there may be announced or un-announced in-class quizzes which will also be graded. A closed book, in-class final exam will be given at the time indicated in the TIME TABLE of CLASSES. This section of Math 2214 will not be required to take the common time final exam.


NO MAKE-UP EXAMS, QUIZZES or HOMEWORK will be given. Any excused work will be replaced by a grade determined from a portion (or perhaps all) of the final exam. The one hour exams will determine no more than 70% of the course grade. Homework and/or quizzes will determine no more than 20% of the course grade. The final will determine no more than 40% and no less than 30% of the course grade. The final exam will cover all topics discussed in the course. An average grade of 90, 80, 70, 60 guarantees a course grade of A-, B-, C- or D-, respectively.


STUDENT RESPONSIBILITY: It is assumed that each student reads the textbooks and works all the assigned problems. The student is responsible for ALL MATERIAL covered in class and any assigned reading. Students may discuss homework problems. However, it will be assumed that any homework problem turned in for a grade will be the students own work. All exams are to be pledged. Any messy, sloppy and/or otherwise unreadable work will receive ZERO points. Virginia Tech Honor System: The Virginia Tech Honor System will be strictly enforced and applies to all graded work in this course. Specifically: all exams must be solely the individual student's work; homework may be discussed with others, but the final submitted product should be the student's own work; any other assignments will be explicitly noted as to whether collaboration is permissible or not. Among other things, the Honor Code prohibits giving or receiving unauthorized aid, assistance, or unfair advantage on academic work and it prohibits plagiarism. Under the Honor Code it is the responsibility of each student to consult with his/her teacher, if necessary, to ensure that the student understands exactly how the Honor Code applies to each piece of graded work.


IMPORTANT: If you are not on the class roll that comes out after the last add date, immediately check your schedule at a terminal and start attending the proper section. For no foreseeable reason (computer and registrar personnel mistakes included) will you be allowed to stay in the wrong section or to drop a section for which you are actually enrolled after the last drop date. By simply attending a section you will not be placed on its roll.
