Abstract
We routinely use our calculator to obtain the sine of a given angle. (In earlier times we used published tables!) Little do we realize that a debt of gratitude is owed to the fifth century Indian savant Aryabhata who was the first to tell us about the sine function and create the first table of sines — in his seminal work, the Aryabhatiya (499 CE). In this article, we describe the trigonometric identities used by Aryabhata to obtain the table of sines.
