From the preamble: The main thrust for publishing a second edition of this book was to facilitate the process of learning this material, both in the classroom or in a self-teaching environment. The book covers the same basic theoretical concepts, but we have added a large number of exercises, including solved exercises that appear in the sections titled “Practice exercises.” These exercises are based on prototypical problems and guide the student toward answers that are correct, precisely stated, and succinct. We also took this opportunity to reorganize a few lectures and correct many typos. Most typos were annoying but inconsequential, but a few could be misleading. A special thanks to all the students that got back to me with typos, requests for clarification, and other suggestions for improvement.
