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
Bachelor of Mathematics mathematics. Relatively few institutions award Bachelor of Mathematics degrees, and the distinction between those that do and those that award B.Sc or B.A. degrees for mathematics is usually bureaucratic, rather than curriculum related. However, schools that offer Bachelor of Mathematics degrees argue for a separate degree, maintaining that the study of mathematics is vastly different from other fields. Australia Bangladesh Canada India Netherlands Russia United States Philippines Ghana Bachelor of Mathematics A Bachelor of Mathematics is an undergraduate academic degree awarded for successfully completing a program of study in mathematics or related disciplines, such as computer science or statistics.
