For two-term, or condensed one-term, freshman/sophomore-level courses in Finite Math and calculus. This mathematically correct, accessible, and student friendly text prepares students for the math they will encounter as they matriculate through a wide range of disciplines. The text's optional graphing calculator material is presented thoughtfully and makes Barnett ideal in course employing the graphing calculator. The emphasis throughout is on computational skills, ideas, and problem solving-rather than mathematical theory. Most derivations and proofs are omitted except where their inclusion adds significant insight into a particular concept. General concepts and results are usually presented only after particular cases have been discussed.
