History of PieThe French mathematician Francois Vieta (1540-

1603), the first mathematician to us symbolic notation for known as (constants) and unknowns

discovered the first direct formula for the calculation of π.

π2=112√12+1212√√12+√1212+1212...√√π2=11212+121212+1212+1212...

The Ancient Greek math value of pimatician Archimedes of Syracuse (287-212 BC) is the first to calculate an accurate estimation.Sulva Sutra also gave methods of constructing a square whose area equals the area of a given circle. The construction involved approximating π the value used is 3.088,which is quite closer to the real value of π. By P. Rohit

History of Pi The number π is a mathematical

constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi“.

History of Pi Being an irrational number, π cannot be

expressed exactly as a fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern). Still, fractions such as 22/7 and other rational numbers are commonly used to approximate π. The digits appear to be randomly distributed; however, to date, no proof of this has been discovered.

History of PiThroughout the history of mathematics, one of the most enduring challenges has been the calculation of the ratio between a circle's circumference and diameter, which has come to be known by the Greek letter pi.  We will probably never know who first discovered that the ratio between a circle's circumference and diameter is constant, nor will we ever know who first tried to calculate this ratio. The word literally means "rope-stretchers" or "rope-fasteners.“

History of PiThe misinterpretation is that these men were stretching ropes in order to calculate circles, while they were actually making measurements in order to mark the property limits and areas for temples, according to a famous Egyptian piece of papyrus gives us another ancient estimation for pi.
