Title: this is " thomas calculus" as written by thomas himself-recommended
Review: This is an early version of the book that made "thomas' calculus" the standard for years, as the engineer's basic training ground. not to be confused with the hundreds of mostly inferior later versions written by others with thomas' name tacked on. these used to be available for a couple of bucks. but beware, i have seen other books now also called "alternate edition" that seem to be later editions of non recommended versions.
