Who discoved trignometry?
About 100 b.c., during the period of the Alexandrian Greeks, the Greek astronomer Hipparchus developed what is today called spherical trigonometry. The Greek astronomers used spherical trigonometry to determine the time of day, direction of motion, and the positions of ships or reference points. Greek trigonometry flourished in the following centuries, reaching its highest point with the astronomer Menelaus (first century a.d.) and his successor, Ptolemy. Following the decline of Greek civilization about 640 a.d., little progress occurred until the advancement of science and mathematics recommenced during the Renaissance, beginning approximately in 1400.
