Textbook: Elementary Differential Equations and Boundary Value Problems, by W. E. Boyce and R. C. DiPrima, John Wiley & Sons, 8th Ed.


Grading: There will be two semester tests and the Final Exam. The break up of your course grade is as follows:
Test 1 25%
Test 2 30%
Final Exam 35%
Quizzes 10%
Your grade will be determined according to the standard scale
A 90-100
B 80-89
C 70-79
D 60-69
F 59 and lower
Note that the above numbers are percentages of the highest possible score in the course.

Quizzes: Be prepared for short quizzes (1-2 problems, about 10 minutes).

Homework will be assigned on a daily basis (see the schedule) and may be collected periodically. It is required that you complete all homework.

Make-up Exams are given only in cases of serious illness, family death, etc. Contact me immediately if you need to arrange for a make-up.

Technology: You will find that mathematical software is very useful for visualization and computations in this course. Any of the following packages is sufficient for our purposes: MATLAB, Maple, or Mathematica.
