You can derive most of them from directly the pythagorean identity. Just remember that one and you'll be set.

Don't listen to this guy, memorize the law of cosines instead. With that and the complex exponential you can derive the rest of trigonometry from first principles if you have to. Definitely don't bother memorizing the sine of 17x in terms of the sine of x, for instance,. It won't help you to understand anything the way just those two formulas do.
