Exams

There will be two in-class midterms and a final. There will be no makeup exams.

Midterm 1

Midterm 1: Wednesday, April 23, 2:10–3:00 p.m.

Midterm 1 will cover the following topics.

Midterm 1: Sample exam

Solutions to sample midterm questions

Midterm 1: Solutions

Midterm 2

Midterm 2: Wednesday, May 21, 2:10–3:00 p.m.

Midterm 2 will cover Sec. 3.1–3.6 and 3.8 on second order linear ODEs:

Midterm 2: Sample questions 1 (Questions 4, 6 are not representative of the material we've covered this quarter)

Midterm 2: Sample questions 2 (Question 5 is not representative)

Solutions: Sample midterm questions 1

Solutions: Sample midterm questions 2

Solutions: Midterm 2

Final

Final (Exam Code B): Saturday, June 7, 10:30 a.m. – 12:30 p.m. The final exam will be comprehensive. Topics covered will be those listed above for the midterms plus material on linear systems: These topics will be emphasised a little on the final in comparison with the earlier topics.

Final: Sample questions 1

Solutions: Sample questions 1

Final: Sample questions 2 (Ignore Question 10 on variation of parameters, which we didn't cover this quarter)

Solutions: Sample questions 2 (Unfortunately, the solutions I have don't exactly match the questions)

Solutions: Final Exam

Homework

Homework problems will be assigned on this web page, but homework will not be collected or graded. Selected homework solutions will be posted after the suggested completion date.

Course Grade

The course grade will be based on (weights in parentheses):

Text for Math 22B

Elementary Differential Equations and Boundary Value Problems, William E. Boyce and Richard C. DiPrima, Eighth edition, John Wiley & Sons, 2005.

The course will cover Chapters: 1, 2, 3, 6, 7

The department syllabus gives a detailed outline.

The publisher has a companion web site for the text, which includes Maple, MATLAB and Mathematica files for ODEs, and information about the ODE architect software included with the text.

An additional resource for Math 22B is Craig Tracy's Lectures on Ordinary Differential Equations.

Computer Accounts

The class will not have assignments that involve computation. However, if you want to use numerical packages such as MATLAB to increase your understanding of differential equations, you can sign up with the mathematics department for a class account.

I will post some simple MATLAB files for ODEs here, or you can write your own.
