Multivariable Calculus from Graphical, Numerical, and Symbolic Points of View

Book excerpt: The text addresses a general mathematical audience: mathematics majors, science and engineering majors, and non-science majors. [The authors] assume little more mathematical maturity than for single-variable calculus, but the presentation is not rigorous in the sense of mathematical analysis. [They] want students to encounter, understand, and use the main concepts and methods of multivariable calculus and to see how they extend the simpler objects and ideas of elementary calculus ... [They] assume that students have the "usual" one-year, single-variable calculus preparation, but little or nothing more than that.-About this preliminary ed
