Differential Equations and Boundary Value Problems, 4th edition, by Edwards & Penney, Pearson - Prentice Hall

Course Description

The lectures will cover *selected* topics from the first seven chapters in the textbook, such as: first-order differential equations and applications; second-order linear differential equations and applications; series solutions; the Laplace transform; linear systems of differential equations and stability. Numerical methods for solving differential equations will also be introduced.
Prerequisites: A solid background in Calculus (Math 135, 136 and 235)
In order to do well in the course, you will need in particular to review basic techniques of integration.

Tentative Syllabus


Homework will be assigned every Thursday and are due the following Thursday.
Part of your homework score will
be determined based on one or two in-class problems that will be assigned on a weekly basis.
No late homework will be accepted. However, the lowest two homework scores will be dropped.
Note that not all problems will necessarily be graded.

Important: it is your responsibility to show your work and to present it in readable form. Answers without justification will receive no credit.


There will be 2 midterm exams and a comprehensive final exam.

  • First midterm exam: October 01, 2013
  • Second midterm exam: November 14, 2013
  • Final exam: Tuesday, Dec 17, 2013 (Comprehensive)

All midterm exams will take place in the classroom during regular class time.
The final exam will take place in the classroom on Tuesday, Dec 17, from 1:40pm to 4:10pm.

Exams must be taken on the scheduled date. There will be no make-up exams, unless extenuating circumstances exist and arrangements have been made prior to the exam.
No books, notes, tables or calculators (of any sort) will be allowed on any of the exams.


Your course grade will be determined by your score in the final exam (200 points), 2 midterm exams (100 points each) and homework (150 points). This is a total of 550 points, earning at least 60% of your 550 points guarantees that you will NOT fail the course.
Bonus points will be awarded based on class participation and effort (e.g., attendance to class and office hours, asking questions, etc).

Disability services

Students with disabilities should notify me as soon as possible of any special needs. They should also provide me with their letters of certification from the Office of Disabilities (Main Hall 105, phone: 255-3354) within the first two weeks of class.

Extra help

A Supplemental Instruction (SI) component is provided for all students who want to improve their understanding of the material taught in this course. SI sessions are led by a student who has already mastered the course material and has been trained to facilitate group sessions where students can meet to compare class notes, review and discuss important concepts, develop strategies for studying and prepare for the exams. Attendance at SI sessions is free and voluntary. Students may attend as many times as they choose. SI sessions begin the second week of class and continue throughout the semester. A session schedule will be announced in class. For information about the program and session schedule/updates, visit:

Ryder Tam will lead regular SI sessions on Mondays from 4:30pm to 6pm in ENG 187 and on Wednesdays from 4:30pm to 6pm (room to be announced).

Additional SI sessions will be held by me in ENG 187. Typically, they will take place on Wednesdays, from 1:40pm to 2:55pm.
Sessions will be announced on the course website, please check it regularly.

Please also note that free tutoring service is avaliable at the Math Learning Center (MLC) located at ENG 233. Fall semester hours and other information about the MLC can be found at

A word of caution

This course turns out to be very difficult. To do well, you should:
- Review background material;
- Study regularly;
- Read ahead each topic before class;
- Come to *every* class and ask questions;
- Review the material afterwards, stressing the understanding of concepts;
- Do the homework regularly;
- Seek help (from me or your SI or your classmates) when you don't understand something.
You are welcome (in fact, encouraged) to review with others and help each other. Note, however, that everything you turn in should be your own work.
