The first known proofs of an infinite series expansion were devised here, in what came to be known as the Kerala school of astronomy and mathematics. Madhava of Sangamagrama ( ; ), was an Indian mathematician-astronomer from the town of Sangamagrama (present day Irinjalakuda) near Cochin, Kerala, India.
Madhava-Gregory series (RC Gupta in a math journal, 1973) Madhava’s other contributions come from a variety of scholars and include: Trigonometry – table of sines and values of half-sine chords for 24 arcs drawn at equal intervals in a quarter of a given circle.
However, most of Madhava's original work (except a couple of them) is lost. Madhava of Sangamagrama Wikipedia open wikipedia design. Although born in Cochin on the Keralese coast before the previous four scholars I have chosen to save my discussion of Madhava of Sangamagramma (c. 1340 - 1425) till last, as I consider him to be the greatest mathematician-astronomer of medieval India. Madhava of Sangamagrama has appeared in the following books: Significant Figures: The Lives and Work of Great Mathematicians and The Story of Mathematics He was the first in the world to use infinite series approximations for a range of trigonometric functions, which has been called the "decisive step … His writings were later transmitted to Europe via Jesuit missionaries and traders who were active around the ancient port of Muziris at the time. As a result, it had an influence on later European developments in analysis and calculus. It’s a discovery that serves as a precursor to calculus.
In 14th century Kerala, the astronomer and mathematician Madhava of Sangamagrama (1349-1425) can lay claim to the title of the man who knew infinity.
Although there is some evidence of mathematical work in Kerala prior to Madhava (e.g., Sadratnamala c. 1300, a set of fragmentary results), it is clear from citations that Madhava provided the creative impulse for the development of a rich mathematical tradition in medieval Kerala.
