Mathematical Treasure: The Tantrasangraha of Nilakantha

Frank J. Swetz (The Pennsylvania State University)

The Kerala School of Mathematics and Astronomy flourished in Southern India in the fourteen and fifteenth centuries. Among its participants was the astronomer and mathematician Neelakanta Somayaji (1444-1544) who is credited with developing series expansions for the common trigonometric functions. His best known work, written on palm leaves, is called Tantrasangraha [or Tantrasamgraha] (1501).
