The author of this title 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. New titles are being added to Barron's ongoing "E-Z" project, which entails updating the older, highly popular "Easy Way" books with improved content and handsome new designs. New cover designs reflect the brand-new interior layouts, which feature extensive two-colour 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. In addition to their self-teaching value, these books are also widely used as textbooks or textbook supplements in classroom settings. "E-Z" books review their subjects in detail, using both short quizzes and longer tests to help students gauge their learning progress. The exercises and tests come with answers. Subject heads, key phrases, and graphics are set in a second colour.
