An experienced maths teacher breaks down precalculus into a series of easy-to-follow lessons designed for self-teaching and rapid learning. The book features a generous number of step-by-step demonstration examples as well as numerous tables, graphs, and graphing-calculator-based approached. Major topics covered include: algebraic methods; functions and their graphs; complex numbers; polynomial and rational functions; exponential and logarithmic functions; trigonometry and polar coordinates; counting and probability; binomial theorem; calculus preview; and, much more. Exercises at the end of each chapter reinforce key concepts while helping students monitor their progress. Charts, graphs, diagrams, instructive line illustrations, and where appropriate, amusing cartoons help to make learning E-Z. "Barron's E-Z" books are self-teaching manuals designed to improve students' grades in a wide variety of academic and practical subjects. For most subjects, the level of difficulty ranges between senior school and college-101 standards. E-Z books review their subjects in detail, and feature both short quizzes and longer tests with answers to help students gauge their learning progress.
All exercises and tests come with answers. Subject heads and key phrases are set in a second color as an easy reference aid.
