4th Edition Douglas Downing, Ph.D.  All books by this author Barron’s EZ Series  All books in this series Known for many years as Barron’s Easy Way Series, the new editions of these popular selfteaching titles are now Barron’s EZ Series. Brandnew cover designs reflect all new page layouts, which feature extensive twocolor treatment, a fresh, modern typeface, and more graphic material than ever— charts, graphs, diagrams, instructive line illustrations, and where appropriate, amusing cartoons. Meanwhile, the quality of the books’ contents remains at least as high as ever. Barron’s EZ books are selfhelp manuals focused to improve students’ grades in a wide variety of academic and practical subjects. For most subjects, the level of difficulty ranges between high school and college101 standards. Although primarily designed as selfteaching manuals, these books are also preferred by many teachers as classroom supplements—and for some courses, as main textbooks. EZ books review their subjects in detail, and feature both short quizzes and longer tests with answers to help students gauge their learning progress. Subject heads and key phrases are set in a second color as an easy reference aid. Barron’s EZ Trigonometry explains angles and triangles, and demonstrates the solutions to right triangle problems. Chapters that follow deal with trigonometric functions of sine, cosine, and tangent, radian measures, Pythagorean and other trigonometric identities, graphs of trigonometric functions, waves, polar coordinates, complex numbers, conic sections, spherical trigonometry, polynomial approximation for sin x and cos x, and more. Exercises follow every chapter with answers given at the back of the book. Table of Contents:
