it's only 6:53

no ffff. must study math @__@

*bombards you with trig*

cos(A-=cosAcosB+sinAsinB

*B )

sin(A+B )=sinAcosB+cosAsinB

tan(A+B )= tanA+tanB/(1-tanAtanB)

ohohoho

i hate trig. on to permutation.

nCr=n!/(n-r)!

wait dammit

*nPr

nCr is actually n!/r!(n-r)!

*obviously not doing this to spite you*

And the one for repeated trials is nCrp^(r)q^(n-r)

*is actually copying most of this off her notebook* 8D /CHEATER

Repeated trials is for probability lol *confuses self*

sohcahtoa!!!!

but there's also caoshacho!!!1
