Trigonometry Workbook For Dummies

File Size: 2.68 Mb

Description
What in the world is trigonometry? Well, for starters, trigonometry is in the world, on the world, and above the world — at least its uses are. Trigonometry started out as a practical way of finding out how far things are from one another when you can’t measure them. Ancient mathematicians came up with a measure called an angle, and the rest is history.

So, what’s my angle in this endeavor? (Pardon the pun.) I wanted to write this book because trigonometry just hasn’t gotten enough attention lately. You can’t do much navigating without trigonometry. You can’t build bridges or skyscrapers without trigonometry. Why has it been neglected as of late? It hasn’t been ignored as much as it just hasn’t been the center of attention. And that’s a shame.

Trigonometry is about angles, sure. You can’t do anything without knowing what the different angle measures do to the different trig functions. But trigonometry is also about relationships — just like some of these new reality television shows. Did I get your attention? These relationships are nearly as exciting as those on TV where they decide who gets to stay and who gets to leave. The sine gets to stay and the cosecant has to leave when you know the identities and rules and apply them correctly. Trigonometry allows you to do some pretty neat things with equations and mathematical statements. It’s got the power.
