The author of this imaginative self-teaching book tells an entertaining story about travels in the fictional land of Carmorra. In the process he introduces a series of problems and solves them by applying principles of calculus. Readers are introduced to derivatives, natural logarithms, exponential functions, differential equations, and much more. Skill-building exercises are presented at the end of every chapter. Books in Barron's new E-Z series are enhanced and updated editions of Barron's older, highly popular Easy Way books. New cover designs reflect the brand-new interior layouts, which feature extensive two-color treatment, a fresh, modern typeface, and more graphic material than ever. Charts, graphs, diagrams, line illustrations, and where appropriate, amusing cartoons help make learning E-Z in a variety of subjects. Barron's E-Z books are self-teaching manuals focused to improve students' grades in skill levels that range between senior high school and college-101 standards.
