Do you think I could just leave this part blank and it'd be okay? We're just going to replace the whole thing with a header image anyway, right?

Trig help math people get in here
Okay so I tried brute forcing the problem, that didn't work, so I tried thinking at it, that obviously didn't work, so now it's time to make a topic on the forums.
If I have two sides of a right triangle, x and y, and the hypotenuse is always 1. is it possible to get a value from 0-1 out of that with some magical inverse trig functions? x=1 y=0 should spit out 0, x=0 y=1 should spit out .25, x=-1 y=0 should spit out .5, and x=0 y=-1 should spit out .75. I feel like this is really basic stuff as far as trig goes but eh.
tl;dr: how do I this?

((arccos(x) + arcsin(y))/pi)/2
EDIT: and make sure it's in radians
