Make trigonometry as easy as 1-2-3.

Believe it or not, trigonometry is easier than it looks! With the right help, you can breeze through your next trig class, test, or exam and be ready for your next math challenge. In Trigonometry For Dummies, you'll learn to understand the basics of sines, cosines, and tangents, graph functions, solve tough formulas, and even discover how to use trig outside the classroom in some cool and interesting ways.

Many of the exciting and, yes, practical accomplishments of early humans were performed using trigonometry. Even before it was formalized into a particular topic to study or used to solve problems, trigonometry helped people to sail across large bodies of water, build gigantic structures, plot out land, and measure heights and distances — even to the stars. We still use trigonometry for all these reasons and more. For example, if you’re going to get your pilot’s license, you’ll need trigonometry. Trigonometry is also the basis for many courses in mathematics — starting in grade school with geometric shapes and map reading, and moving on through calculus. Trig is all over the place.

You can get as deeply into this topic or as little into it as you want, and you’ll still come out of it thinking, “Gee, I didn’t realize that trigonometry was used to do this! Wasn’t that just loads of fun!” Well, maybe I’m pushing it a bit — loads may be a slight exaggeration.

Whether you’re pursuing trigonometry so that you can go on to calculus or prepare for architecture or drafting or do that piloting thing, or you’re just curious, you’ll find what you need here. You can get as technical as you want. You can skip through the stuff you don’t need. Just know that you’ll be on the same adventure as those early humans — you’ll just have the advantage of a few more tools.

Ditch the confusing jargon and take a plain-English tour of one of the most useful disciplines in math. In this lifesaving guide, you'll learn how to:
• Graph trig functions, including sine, cosine, tangent, and cotangent functions
• Understand inverse trig functions and solve trig equations
• Relate triangles to circular functions and get a handle on basic identities

So, whether you're looking for an easy-to-use study guide, to boost your math grade, or get a refresher on some basic trig concepts after a long absence from studying, Trigonometry For Dummies is your ticket to understanding the mathematical mysteries of the triangle.
