Students and math professors looking for a calculus resource that sparks curiosity and engages them will appreciate this new book. Through demonstration and exercises, it shows them how to read equations. It uses a blend of traditional and reform emphases to develop intuition. Narrative and exercises present calculus as a single, unified subject. Color is used to help them identify and interpret the parts of a mathematical model. In addition, formal proofs are preceded with informal discussions that focus on the ideas about to be presented. Then the proofs are discussed in a way that helps scientists and engineers interpret the details of the argument.
