The distinguishing features of the book are the focus on the concepts, essential functions and formulas of calculus and the effective use of graphics as an integral part of the exposition. Formulas that are not significant and exercises that involve artificial algebraic difficulties are avoided.
The three-volume calculus sequence is organized as follows:
-Calculus I covers the usual topics of the first semester: limits, continuity, the derivative, the integral and special functions such as exponential functions, logarithms and inverse trigonometric functions.
-Calculus II covers techniques and applications of integration, improper integrals, infinite series, linear and separable first-order differential equations, parametrized curves and polar coordinates.
-Calculus III covers vectors, the differential calculus of functions of several variables, multiple integrals, line integrals, surface integrals, Green's Theorem, Stokes' Theorem and Gauss' Theorem.
