Forgoten INDIAN HERO

Iriññāttappiḷḷi Mādhavan Nampūtiri known as Mādhava of Sangamagrāma (c. 1340 – c. 1425) was an Indian mathematician and astronomer from the town believed to be present-day Aloor, Irinjalakuda in Thrissur District, Kerala, India.
He is considered the founder of the Kerala school of astronomy and mathematics.
One of the greatest mathematician-astronomers of the Middle Ages, Madhava made pioneering contributions to the study of infinite series, calculus, trigonometry, geometry, and algebra.
He was the first to use infinite series approximations for a range of trigonometric functions, which has been called the "decisive step onward from the finite procedures of ancient mathematics to treat their limit-passage to infinity".
Some scholars believe that Jesuit missionaries and traders who were active around the ancient port of Muziris at the time transmitted his writings to Europe. As a result, it may have had an influence on later European developments in analysis and calculus.
