Āryabhaṭa's sine table
FIRST SINE TABLE EVER CONSTRUCTED
Aryabhata's table of sines; Aryabhata sine table; Aryabhata's sine table; Aryabhata' s sine table
The astronomical treatise Āryabhaṭīya was composed during the fifth century by the Indian mathematician and astronomer Āryabhaṭa (476–550 CE), for the computation of the half-chords of certain set of arcs of a circle. It is not a table in the modern sense of a mathematical table; that is, it is not a set of numbers arranged into rows and columns.
