Reblog: Multivariable Calculus


I believe that I used this textbook, or at least one similar to it, in learning Multivariable Calculus. (Admittedly there are certain similarities among introductory textbooks on this subject which can’t be avoided.) Still, it should be useful for people not sure how you get from coordinate pairs to proving swiftly that the force of gravity on the inside of a solid-shell style Dyson sphere is zero.
