This third edition of Alfred Gray's famous textbook continues to offer an outstanding presentation of how to define and compute standard geometric functions along with a dialect of Mathematica for constructing new curves and surfaces from existing ones. Since Gray's death, authors Abbena and Salamon have stepped in to bring the book up to date. While maintaining Gray's intuitive approach, they have reorganized the material to provide a clearer division between the text and the Mathematica code, added a Mathematica notebook as an appendix to each chapter, and addressed important new topics,...
