More Basic Trig

Every angle has a sin or cosine or tan (well, not quite every angle, in the case of tan). You can use this value to find the angle, doing it easily on a calculator.

You just press sin-1 .456 or whatever it is, and that gives you the angle (if you have the calc. set to degrees that is).

Is it bad that my calculator is musical and has pictures of animals on it?

Um, yes, I'm afraid it is. Very bad. You are probably a humanities graduate.

This is a fatal condition, and there is neither treatment nor cure.

Trust me, I know.

If you are patient, I'm willing to learn...despite my humanities flaws...

Good call on that, Tin Tin.
