Trig without Tears
How to remember trigonometric identities. I believe it is much more effective (and, in the long run, much easier) to understand thoroughly how the trig functions work, memorize half a dozen formulas, and work out the rest as needed.
The trigonometric functions are very important in technical subjects like science, engineering, architecture, and even medicine. You will come across trig functions all the time and you are encouraged to learn them well! Bored? Try the Math Games near the bottom of this page.
I am a theoretical physical chemist. Chemists use trigonometry routinely to interpret spectroscopic probes of molecules and use them to figure out molecular structures. Without trigonometry we would know very little about chemistry!
If you would just like one page to print out with all the trig definitions, this is your page. This site also has an iPhone app for trig and other calculations for a small fee.
When you understand this animated diagram, you shall understand the sin(x).
Uses of trigonometry
Knowledge of nearly nothing beyond trigonometry itself is enough to make clear the nature of some of the applications of trigonometry to such endeavors as navigation, land surveying, building, and the like, but that impression is misleading in that it fails to indicate the nature and enormous variety of the other scientific applications and other uses of trigonometry.
