WebHipparchus (190–120 B.C.E.) produced the first trigonometric table for use in astronomy. It was a table of chords for angles in a circle of large fixed radius. Incidentally, his table was not in terms of degrees, but “steps”, each step being 1/24 of a circle. Later, Ptolemy (100–178 C.E.) constructed a more complete table of chords.
