Solutions
Be careful! It is easy to misuse solutions so that no learning results. The point of homework is not to "get the answer." It is to learn. Learning includes understanding the concepts and how to get the answer.
It is a serious mistake to look at the answers before putting significant effort into the problems. Anyone can look at an answer and agree "I see how that's done" or "Yes, that's right." That is a far cry from doing it yourself.
I hesitate to provide these pdf files of solutions to selected problems. It will help some good students who use it wisely. It will hinder those of you who look up answers too rapidly.
A pdf file of some solutions to problems in Chapter 1.
A pdf file of some solutions to problems in Chapter 2.
A pdf file of some solutions to problems in Chapter 3.
By the way, there will be no such solution-files for Chapters 4 and 5.
