c8.s3.65

In western mathematics Newton ( 1642-1727 ) is often given credit for the expansion of sine and cosine series No. ( 3 ). The result was established later algebraically on a solid foundation by De Moivre ( 1707-38 ) and Euler ( 1748 ). It is clear from the discussion that the Indian scholar Mādhava ( 1350-1410 ) used and possibly established the series (1), (2) and (3) of course in finite form before Newton, De Moivre and Euler, and laid the foundation of his sine table.
