Lecture 3, September 7, 2010.
Here is a pdf file with a computer presentation used in the lecture.
Warnings:
1. Do not print it, but read on a computer screen using Adobe acrobat or xpdf or similar software. If you would try to print it, then you would get lots of pages which almost repeat each other.
2. This is not a complete recording of the lecture. Read Chapter II of the textbook.
