    the arcsin function has a range of -pi/2 to pi/2 So it only gives you values if sin between -pi/2 and pi/2

    basically, we take a section of the sin graph that we can use for an inverse function

    and by convention, that part is between -pi/2 and pi/2

    Oh Ok thanks once again :] one more question for the Sin graph of that like sideways S thing do you know the order at which the X axis is like the pi/2 and pi and stuff

    i got that a little backwards; the pi/2 stuff is the output and should be on the y's the x axis should normally be for -1 to 1
