This three-semester calculus textbook presents the principles and applications of calculus. Topics include: continuity and limits, differentiation and integration of algebraic and trigonometric functions, fundamental theorem of the calculus, applications of the derivative to curve sketching, rectilinear motion, maximum/minimum problems, and related rates, applications to the integral to problems of area, volume, arc length, and work. In addition to the beginning concepts of calculus this text also provides instruction in the differentiation and integration of transcendental functions, standard techniques of integration, curves in polar coordinates, and sequences and series, multivariable calculus, partial differentiation, two- and three dimensional vectors, Stokes and divergence theorems, and differential equations
