arcsin is the opposite of sin. if you have something thats say, sinx=9, you would do the arcsin of 9 to find x. same with arccos and arctan.

The sin of 90 (pi/2) = 1
the arcsin of 1 is 90 .
The sin of 45 (pi/4) is sqrt 2 / 2.
The arcsin sqrt 2 / 2 is 45.
If the sine of x degrees or x/180 radians is B,
then the arcsin of B is x degrees or x/180 radians.
Thats all there is too it

If Y = sin(X)
Just to review Y will keep repeating the same values as X increases. That is to say sin(x) = sin(x + 2Pi)
Now the inverse function is
X = arcsine(Y). X can have many values.
So to truly make arcsine a function we have to restrict X to the value nearest to zero.
