Narayana (mathematician)
Narayana was a 14th century Indian mathematician . He is considered one of the most important medieval mathematicians in India outside of the Kerala school.
Little is known about him. He was the son of Nrsimha (or Narasimha).
He is best known as the author of a book on arithmetic and geometry Ganita Kaumudi from 1356. It contains, for example, methods of squaring numbers (often treated independently of multiplication methods by the Indians ), he gave formulas for triangles with integer sides and additional conditions, treated number sequences such as arithmetic progressions (in a chapter Network of Numbers ), methods of approximate calculation of square roots (using Pell's equation ), a formula for a segment of a circle and the last chapter deals with magic squares .
He is often ascribed the Karmapradipika , a commentary on the Lilavati by Bhaskara II. Others suspect Madhava as the author. There is also a Bijaganitavatamsa by Narayana , a book on algebra preserved in an incomplete manuscript.
