The author has designed this text to be one students want to read - and actually do read because of the patient explanations, useful tools, and applications. Numerous examples and solved problems are used to amplify each new concept, and figures are used extensively to help students visualize the ideas being presented. Like COLLEGE MATHEMATICS, FOURTH EDITION and other texts in the respected Tan series, APPLIED CALCULUS, FOURTH EDITION includes a wealth of interesting and relevant applications drawn from the fields of business, economics, and the social, behavioral, life, and physical sciences. More than enough material is included for the typical applied calculus course, so instructors can design a course that meets their needs (optional sections are marked in the table of contents). For those instructors who want to integrate technology into their course, this edition includes optional graphing utility exercises and examples.
