Many Indian mathematicians calculate the approximate value of π. The value of π stated by Aryabhata – I was accepted by all the mathematicians which is (π = 22/7). Indian mathematicians used different methods to find the values of π. Madhava of Sangamgram of Kerala calculated the value of π in terms of infinite series. This method of finding the value of π is the beginning of idea of calculus in India. These methods are found in the text Yuktibhasha of Jyesthadeva (1500–1610 ad.), Tantrasangraha of Nilakantha (1443–1560 ad.), Kriyakramakari of Sankara Variyar (1500–1560 ad.). We have discussed here three methods of finding the value of π and also calculus involved in it. These three methods cover the idea of infinitesimal calculus. These methods are as follows.
