This book is small, expensive and relatively bad. While there are plenty of errors to be annoyed by (everything from incorrect solutions to syntax errors in the mathematics), my main qualm with the book comes from the poorly motivated text. While the underlying structure is suitable, the overall exposition is crap. The text reads like lecture notes, and I don't think it is quite up to the standard of a textbook. The exercises also need some work; there should be more exercises that are more interesting. As a mathematics major I am not all too impressed with it, but a student of an applied science may like it more. Although in this form I don't think it is suitable for any audience.If you want to learn Vector Calculus, I would suggest the multivariable/vector analysis sections of Stewart's Calculus text. That is where I learned the material. Vector Calculus by Marsden also seems promising, but I have not read it all yet.
