ack, need help with inverse sin

Im using the math.h file to do some vector addition, i need to get the inverse sin of something, what do i call to do it?

Replys asap please, as I just noticed what I had was wrong :(.

Thanks!

>i need to get the inverse sin of something
The asin() function calculates the inverse sine in radians.

Thanks, i was looking through explainations of the functions, i've never heard of arcsin though, so wasnt sure, thank you.

Never heard of arcsin??? :p

How about sin(x)^-1 :D

arcsin and vector addition? you must be using some arse nasty vectors! (physics or some other science I bet)

Ahh I wish all vectors were as simple as in linear algebra!

vector v = (1, 2, 3)
vecor w = (2, 3, 4)

v + w = (3, 5, 7)
