Title: Beware of the problems and answers in the back
Review: Freshmen with a semester of AP calculus placement used this book in the fall of 1970 at Yale. Some of the problems were stated ambiguously. Some of the answers in the back of the book were wrong. Students and instructors loved the book so much that it was not used ever again at Yale, not even for the spring semester. That meant we could not even sell it to the next wave of users. The generally agreed best use of the book was to cut out the text area of all the pages, coat that new inner surface with glue, line it with paper or cloth, and use the final result as a place to hide valuables in the dorm. The book's large format and thickness provided quite a bit of room. Furthermore, no visitor was likely to pluck it from your bookshelf.
