Madhava of Sangamagrama contribution to Calculus was much before Europeans.
Madhava of Sangamagrama (c. 1340 – c. 1425), was an Indian mathematician-astronomer from the town of Sangamagrama. 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.
His birth place Sangamagrama is present-day Irinjalakuda near Thrissur, Kerala, India.
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“.
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.
Madhava was born as Irińńaŗappiļļy or Iriññinavaļļi Mādhava . He had written that his house name was related to the Vihar where a plant called “bakuļam” was planted.
Bakuļam was locally known as “iraňňi”.
Irinjalakuda was once known as ‘Irińńāţikuţal’. Sangamagrāmam (lit. sangamam = union, grāmam = village) is a rough translation to Sanskrit from Dravidian word ‘Irińńāţikuţal’, which means ‘iru (two) ańńāţi (market) kǖţal (union)’ or the
