Textbook: Differential Equations (computing and modeling), Fourth Edition, by C. H. Edwards and D. E. Penney.
Prerequisite: A grade of C or higher in Math 142.
Subject Materials: We shall cover most of the material presented in Chapters 1-3 and in Chapter 7 of the text.
Learning Outcome: Students are expected to master mathematical
concepts and apply these concepts to solve problems
of first order and higher order linear ODEs based upon the methods they learn from this class.
Reading: Reading the textbook
in advance of the lecture is strongly
encouraged. Benifits of this preparation include obtaining a familiarity with the terminology and
concepts that will be encountered (so you can distinguish major points from side
issues), being able to formulate questions about the parts of the presentation that
you do not understand, and having a chance to review the skills and techniques
that will be needed to apply the new concepts.
Tentative Schedule
Homework Assignment
Homework and Quiz:
Homework will not be collected, but you are supposed to do them all.
REMEMBER: the more problems you do, the better you understand the material.
Students are encouraged to work together on homework sets.
There will be approximately one quiz per week on Wednesday,
and no quiz during or after the exam weeks.
There are two problems for each quiz.
The quiz problems will be either the same as, or very similar to those
from the homework. Thus, if a student has made a good attempt at the
homework, he/she should do well on the quiz.
Two lowest quiz grade will be dropped from the final grade calculation.
Your cumulative quiz grades will be based on the best eight of ten quizzes.
Exams: There will be three midterm exams and a comprehensive final exam.
Exam 1: Monday, Feb. 8, 11:15AM - 12:05PM
Exam 2: Friday, Mar. 5, 11:15AM - 12:05PM
Exam 3: Monday, April 12, 11:15AM - 12:05PM
Final Exam: Tuesday, May 4, 9:00 AM - 12:00 PM
The exams are "closed book" – no books, no notes, no
graphing calculators, no labtop comptuer or equivalent technology, etc. You
may use the scientific calculator.
Picture I.D. is required and must be presented upon request.
There are no early exams. A make-up exam is only possible for
written legitimate documented reasons of illness, family emergency, or participation
in a University sponsered event.
You must take your exams with the lecture for which you are registered.
