Accuracy checking of the problems and typing of Solutions Manual were done expertly by my former student, Dr. Youngjin Chung. Also contributing considerably to this volume with typing new inserts, assiting with some figures, limited proofreading, and cover design was Errol A. Ugural. Their hard work is much appreciated. I am deeply indebted to my colleagues who have found the text useful through the years and to Bernard Goodwin, publisher at Prentice Hall PTR, who encouraged development of this edition. Copy editing and production were handled skillfully by Carol Lallier and Elizabeth Ryan. Their professional help is greatly appreciated. Lastly, I am very thankful for the support and understanding of my wife Nora, daughter Aileen, and son Errol during preparation of this book.
