This book does it all. Without being overly verbose, it explains div, grad, and curl in concepts clearer and maybe even more precise than you would see in some upper level vector analysis classes. The integral definitions for grad and curl are given and well-justified. Homework problems and a number of examples from E&amp;M give practice and application. It's an easy read, relatively cheap, and I think it's great supplementary material for any math or physics student.
