No. They go as a different function called arcsin(). It means "the angle whose sine is the given fraction of a radius." The important distance is how far from the center (measured perpendicular to the path of the cue ball), the object ball is struck. So, it the object ball is contacted full ball, that distance is zero and the arcsin(0) is 0 degrees of cut. If the object ball is contacted at 15/16ths of the radius from center, the cut angle is about 70 degrees. That's the thinnest hit shown in the diagram.
