Indians invented the sine and cosine functions, discovered most of the standard formulae and identities, including the basic formula for sin (A+B), and constructed fairly accurate sine tables. The next Greek mathematician to produce a table of chords was Menelaus in about 100 AD. The noted Greek astronomers Hipparchus, Menelaus and Ptolomy contributed in advancing the field. He considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or surface , as shown by the inscribed triangle A B C in the figure).
