Thomas’ Calculus: Multivariable – George B. Thoma’s – 12th Edition


This text is designed for the component a three-semester or four-quarter course (math, , and science majors).

Calculus hasn’t changed, but your have. Today’s have been raised on immediacy and the desire for relevance, and they come to calculus with varied mathematical backgrounds. ’ Calculus, Twelfth Edition, helps your students successfully generalize and apply the key ideas of calculus through clear and precise explanations, clean design, thoughtfully chosen examples, and superior exercise sets. offers the mix of basic, conceptual, and challenging exercises, along with meaningful applications. This significant revision features more examples, more mid-level exercises, more figures, and improved conceptual flow.
