The History of Pi Throughout 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. From ancient Babylonia to the Middle Ages in Europe to the present day of supercomputers‚ mathematicians have been striving to calculate the mysterious number. They have searched for exact fractions‚ formulas‚ and‚ more recently‚ patterns in the long string of numbers

History of Pi There are many people who have discovered and proved what pi is. As time goes on people discover more and more of the seemingly random numbers. Four of the people who proved pi are the Liu Hui‚ Archimedes of Syracuse‚ James Gregory‚ and the Bible. The first proof I will be talking about is Liu Hui’s. Liu Hui was a Chinese mathematician whose method for proving pi was to find the area of a polygon inscribed in a circle. When the number of sides on the inscribed polygon increased

It is equal to 3.141592 when shortened‚ but never ends. * Archimedes-One of the major contributions Archimedes made to mathematics was his method for approximating the value of pi. It had long been recognized that the ratio of the circumference of a circle to its diameter was constant‚ and a number of approximations had been given up to that point in time. Archimedes was the first person

π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle’s circumference to its diameter in the Euclidean plane; this is the same value as the ratio of a circle’s area to the square of its radius. It is approximately equal to 3.14159265 in the usual decimal notation. Many formulae from mathematics‚ science‚ and engineering involve π‚ which makes it one of the most important mathematical constants. π is an irrational number‚ which means that its value cannot be
