TITLE: Which multivariable calculus books are heavily oriented at physics?
QUESTION [6 upvotes]: Please recommend multivariable calculus books that are really physics oriented.
My wife is looking to brush up on multivariable calculus, at the same time she needs to brush up on the related physics.

REPLY [2 votes]: Bressoud's Second Year Calculus is probably what you want. The motivation for much of this book is the historical problems that come from physics. This is probably one of the best books I know that integrates physics with mathematics as smoothly as this (pun not intended), and it's great read for both physics and mathematics students. Not to mention, it covers and uses differential forms, a topic used in both mathematics and physics for differential geometry.
