Āryabhata (about 476–550) Indian mathematician, author of one of the oldest Indian mathematical texts. Written in verse, the Āryabhatīya is a summary of miscellaneous rules for calculation and mensuration. It deals with, for example, the areas of certain plane figures, values for π, and the summation of arithmetic series. Also included is the equivalent of a table of sines, based on the half-chord rather than the whole chord of the Greeks.
