Query: Avoid this book in your classes

I just tried to teach a course with this textbook and it was excruciatingly painful. The book is not badly written, but there are so many typographical errors in equations and the problems, that you spend countless extra time either correcting the problem so it can be done, or tossing it out. I hated this. Plus there is no second edition, no erratum, no answer key for the professor, nothing you can use to verify if the author really does mean to have the students solve the problem with these numbers, or if they have made a mistake. I will not use this text book again. Going through the pain of teaching all over again with a new text book will be far less than dealing with this one again.
