Quaternions and spatial rotation of a circle representing a particular rotation angle will be half of the angle represented by that rotation, since as the point is moved from the north to south pole, the latitude ranges from zero to 180 degrees, while the angle of rotation ranges from 0 to 360 degrees. (the "longitude" of a point then represents a particular axis of rotation.) Note however that this set of rotations is not closed under composition. Two successive rotations with axes in the "xy" plane will not necessarily give a rotation whose axis lies in the "xy" plane, and thus cannot be represented
360 Degrees of Billy Paul At 16 I was working with Charlie Parker. He's one of the giants. Coming from a jazz background it was one of the greatest things to happen for any singer because of the fact I took an interest at heart but learned to build on it. When I say that I just didn't want to be labeled as a jazz singer but like my new album, the one that "Me & Mrs. Jones" is on, it's called "360 Degrees of Billy Paul" and that means I'm covering all of the territories." In its November 25, 1972, issue, "Billboard" wrote: "Billy
