maths.

Fxxx trigo. fxxx it. im gonna fail if this goes on. and I dont think im the only one. screw it la.
look at this. makes u go crazy

sin(a+b) = sinacosb+cosasinb
sin(a-b) = sinacosb - sinbcosa
cos(a+b) = cosacosb-sinasinb
cos(a-b) = sinasinb-cosacosb
tan(a+b) = sinacosb+cosacosb/cosacosb-sinasinb
sinacosa = 1/2sin^a
2sinacosa = sin^2a
cos2a = ???
cos4a = ???
cos6a = ???
tan2a = tan^2a/1-tanatanb

I think most of it is wrong heck.

screw old ghost too. 2 compos 1 compre during new year
