/me opens his maths book

you really don't know or are you looking for the real function of sin cos tan? because i dont know the formula either.. i just know how to use them

this formula : soh cah toa
Sin x: Opposite over Hypotenuse
Cos x: Adjacent over Hypotenuse
Tan x: Opposite over Adjacent

this is a typical right angles
'''''''|\
'''''''|'\
'''''''|''\ hypotenuse
'''''''|'''\
'''''''|''''\
'''''''|'''''\
'''''''|'''''x\
''''''''-------'
adjacent

and opposite is the side on the left

well sin cos tan is a formula designed to find the angle given you have information of the sides or one of the side and the angle

i think in flash you use math.sin(blah)
where blah can be a value or a variable

does this help?

thanks UnderTheSun that helps although some pratical examples could make me understand better

[UnderTheSun]

well..
the formula i posted before will help you remember
soh cah toa lol hehehe

i just searched for soh cah toa

here's a really strange overview about sin cos tan theorem (they look like fictional to me) but it would explain

wait just check this one instead

scroll to the middle and you'll understand everything
good luck !
