Grading

Catalyst Gradebook

Your grade will be based equally on homework, two midterms, and a final (the actual weights may change slightly). In all tests you may use one sheet front and back of notes in your own handwriting.

Topics Covered

See the departmental syllabus for more information.

• Review of linear algebra, including eigenvalues and complex numbers.
• Solving first-order linear systems of differential equations
• Stability analysis of first-order differential equations
• Fourier series
• Partial differential equations including heat, wave and Laplace's equation

Textbook

The UW Math department uses a custom edition of Elementary Differential Equations and Boundary Value Problems by Boyce and DiPrima. We will cover chapters 7, 9, and 10 from this book. You may either buy the custom edition available at the UW Bookstore, or you may use any recent edition (7th+ is fine) of the standard book. The edition doesn't matter much for the course readings. However, the problem numbers may change, so if you use an older edition, check with a friend or at the library to make sure you do the right homework problems.

Office Hours

Office hours will be Tuesday and Wednesday, 11:00-12:00. They will be held in the math department lounge in Padelford Hall. If neither of these times works for you, please email me. I may be able to add an additional office hour.
