Calculus: Single and Multivariable, 7th Edition continues the effort to promote courses in which understanding and computation reinforce each other. The 7th Edition reflects the many voices of users at research universities, four-year colleges, community colleges, and secondary schools. This new edition has been streamlined to create a flexible approach to both theory and modeling. The program includes a variety of problems and examples from the physical, health, and biological sciences, engineering and economics; emphasizing the connection between calculus and other fields.
A good text book is one that a student can pick up and use to learn the subject at hand, and this book doesn't even come close. There are a lot of skipped steps and a major chasm where explanation and background should go. There are also a lot of errors in this book (starting with the table of contents and continuing all the way to the end).
That's right, five stars. This is the only calculus book that I would ever want to pick up again. Not simple. Not easy to understand. Nothing was ever explained step by step. But it came with the answers software! And it's easier to work backwards with calculus.
