# Description

A leaner, crisper, more accessible edition (according to the preface), for the widening range of students who need knowledge of the basic concepts. No bibliography. Annotation copyright Book News, Inc. Portland, Or.

This text covers the contents of a calculation course of one and several variables. In this edition the subjects have been adequate for a course of calculation more accessible; historical and biographical notes have been added, as well as projects with graphing calculators and computer labs (with options for Derive, Maple and Mathematica), since experience suggests that the use of technology can make the calculation more concrete and accessible to the students. Likewise, the number of figures has doubled to illustrate a focus of more deliberation and exploration in problem solving.

Thanks a lot. YouÂ´re a great help for all of us.
