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
38 Degrees above a flat-line membership structure. 38 Degrees also claims its campaigns are selected by its members under its "Campaigns by You". David Babbs is Executive Director. He signs off some emails, appears in the media and frequently speaks at local 38 Degrees events. He has also represented 38 Degrees in front of parliamentary select committees. Babbs describes his motivation for campaigning as coming from "a gut feeling that things could be better, politically, socially, and environmentally and that the reason they’re not is largely due to the conscious actions of powerful people rather than due to bad luck or any
