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
36 Degrees and the early legs of the "Meds" tour. It was also released as a B-side to the "Because I Want You" and "Song to Say Goodbye" singles under the title "36 Degrees 2005". It continues to be performed in various arrangements into 2016.
