Ptolemy's table of chords to the arc angle in degrees as is to 3, or more precisely, the ratio can be made as close as desired to ≈ by making "θ" small enough. Thus, for the arc of °, the chord length is slightly more than the arc angle in degrees. As the arc increases, the ratio of the chord to the arc decreases. When the arc reaches 60°, the chord length is exactly equal to the number of degrees in the arc, i.e. chord 60° = 60. For arcs of more than 60°, the chord is less than the arc, until an arc
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
