      <Abstract>Many Indian mathematicians calculate the approximate value of __ampersandsignpi;. The value of __ampersandsignpi; stated by ?ryabhata – I was accepted by all the mathematicians which is (__ampersandsignpi; = 22/7). Indian mathematicians used different methods to find the values of __ampersandsignpi;. Madhava of Sangamgram of Kerala calculated the value of __ampersandsignpi; in terms of infinite series. This method of finding the value of __ampersandsignpi; 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 __ampersandsignpi; and also calculus involved in it. These three methods cover the idea of infinitesimal calculus. These methods are as follows.</Abstract>
