History of pi and Indian contribution

In this present paper I have tried to introduce the early history of pi, the concept and equation of pi .also represent the devotion of Indian scholar mathematicians or astrologers to find the value of pi .Pi has a very long history so much that many great thinkers in the not only in India but also in ancient world were attachment to try and counting pi. The calculation of pi (π) was revolutionized by the development of infinite series techniques in the sixteenth and seventeenth centuries .An infinite series allowed mathematicians to compute pi(π) with much greater precision than Archimedes and other who used geometrical technique. pi has been more ponder, examined and calculated than any other number. The most basic properties of pi(π)where understood in the period of classical Greek mathematical by the time of the death of mathematicians Archimedes in 212 BC. pi (π) has a great importance in mathematics for not only to the measurement of the circle but also in the more advanced mathematics in connection with such topics as continued function ,logarithms of imaginary numbers, and periodic function. Also the concept of Pi is found in many formulae in trigonometry and geometry. It is also found in formulae from other branches of science, such as cosmology number theory statistics, fractals, thermodynamics, mechanics, and electromagnetism.
