Essentials of Trigonometry - With CD (4TH 06 Edition)

Easy-to-understand, ESSENTIALS OF TRIGONOMETRY starts with the right-angle definition, and applications involving the solution of right triangles to help you investigate and understand the trigonometric functions, their graphs, their relationships to one another, and ways in which they can be used in a variety of real-world applications. The accompanying CD-ROM and online tutorials give you the practice you need to improve your grade in the course.

This first-year textbook introduces angles, radian measure, graphs of trigonometric functions, trigonometric equations, oblique triangles and vectors, complex numbers, and polar coordinates. The fourth edition provides uniform problem sets at the end of each chapter and adds appendices on functions, graphs, and sets of numbers. The CD-ROM contains video instruction and a graphing calculator tutorial.

Karl Smith is professor emeritus at Santa Rosa Junior College in Santa Rosa, California. He has written over 36 mathematics textbooks and believes that students can learn mathematics if it is presented to them through the use of concrete examples designed to develop original thinking, abstraction, and problem-solving skills. Over one million students have learned mathematics from Karl Smith's textbooks.
