Trigonometry Demystified 2/E

Demystified is your solution for tricky subjects like trigonometry If you think a Cartesian coordinate is something from science fiction or a hyperbolic tangent is an extremeexaggeration, you need Trigonometry DeMYSTiFieD, Second Edition, to unravel this topic's fundamental concepts and theories at your own pace. This practical guide eases you into "trig," startingwith angles and triangles. As you progress, you willmaster essential concepts such as mapping, functions,vectors, and more. You will learn to transform polar coordinates as well as apply trigonometry in the real world. Detailed examples make it easy to understand the material, and end-of-chapter quizzes and a final exam help reinforce key ideas. It's a no-brainer! You'll learn about: Right triangles Circular functions Hyperbolic functions Inverse functions Geometrical optics Infinite-series expansions Trigonometry on a sphere Simple enough for a beginner, but challenging enough for an advanced student, Trigonometry DeMYSTiFieD,Second Edition, helps you master this essential subject.
