Trigonometry!!!

Yes, I know most of us all 'love' math. But I really do love math. So here is the first guide page I know of on h2g2 that has any of that deadly number-crunching stuff(I searched...there weren't any more).
The esseinal(I never was great in spelling) ratios:
Tangent: ratio of side a/ side b (first 2 letters of ABC)
Sine: ratio of side a/ hypotnuse (or a/c, remember it's really
cold)
Cosine: ratio of side b/ hypotnuse (or b/c, remember this is the
acient ratio)
That said and done, here are some important formulas(oooh, spooky):
The tangent is equal to the sine/ the cosine
a squared plus b squared = c squared (thank pythagoras for that one)
cosine squared plus sine squared = 1
Any other ones would be way over your puny heads(either that or I just don't know them... but I'll blame it on you)
