(476–550?). Indian astronomer and mathematician Aryabhata I was the earliest Hindu mathematician whose work and history are available to modern scholars. Born in 476 in possibly Ashmaka or Kusumapura, India, Aryabhata was one of the first to use algebra. In about 499 he finished the Aryabhatiya, summarizing mathematics as known in his time. Most of this work deals with astronomy and spherical trigonometry; the remainder consists of 33 rules of arithmetic, algebra, and plane trigonometry. He also created a table of sines and worked with indeterminate equations. Aryabhata I died possibly in 550.
