Currently on sale from Amazon.

Content: The heart of this course is to achieve some real understanding of the wave, heat, and Laplace equations. The emphesis will be on mathematical and physical insight and ideas, not complicated formulas.

Prerequisites & Review Material

Exams: There will be two in-class exams, from 12:00-1:20 on

You may always use one 3"x5" card with handwritten notes on both sides
No Final Exam.
