Aryabhata was a fifth-century mathematician, astronomer, astrologer, and physicist who lived during the classical period of Indian mathematics and astronomy. He is regarded as one of the greatest mathematicians of all time and is the earliest Indian mathematician known by name. Aryabhata was born in Pataliputra, Magadha, and flourished during the Gupta dynasty. He wrote several works, including the Aryabhatiya, which is a compendium of mathematics and astronomy that covers arithmetic, algebra, plane trigonometry, and spherical trigonometry. The Aryabhatiya also contains continued fractions, quadratic equations, sums-of-power series, and a table of sines. Aryabhatas work had a profound influence on the development of Islamic astronomy. Although the concept of the place value system was first used in the Bakshali Manuscript, it held a very important place in Aryabhatas work. However, the symbol for zero was not used by Aryabhata, and the use of zero as a "digit" was first used in India during the Gupta Period.
