Pi is an ancient and wonderful Number to the World of Mathematics invented with the Geometrical structure Circle. CIRCLE It is felt that the creation of the Circle is not created by the man himself but came through the inspiration of Nature itself. The shape of Sun‚ Full Moon‚ Eyes are some examples for it. Some basic things : There are 3 major parts to remember. Radius : The straight line drawn to the Circumference of the Circle from the Centre

Introduction: “You can learn more from solving one problem in many different ways than you can from solving many different problems‚ each in only one way.” Islamic civilization in the middle ages‚ like all of Europe‚ had a dichotomy between theoretical and practical mathematics. Practical mathematics was the common subject‚ “whereas theoretical and argumentative mathematics were reserved for specialists” (Abedljaouad‚ 2006‚ p. 629). Between the eighth and the fifteenth centuries‚ Islamic civilization

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‚ its area became closer to the circumference of a circle and pi. For finding the side length of an inscribed polygon Liu Hui used a simple formula. (13Ma3) To find the side length of an inscribed polygon of 2n sides‚ if the side length of a polygon with n sides is known he used the following formula: In this formula k stands

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

idea of thinking about a‚“regular polygon” being used to determine the skills of the cow attached to wire‚ perimeter‚ number of sides‚ length of sides‚ length wire and lastly the diameter of the stake all needed to be determined. So how do we the readers solve this? Laubach decided to wrap the polygon in wire this being the number of sides‚ when the wire is unwound its end will be determined as the sequence which readers are familiar to as the radii of our given polygon. After that first step was

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

hundreds of years later that the problems were proved to be actually impossible under the limitations imposed. In 1796‚ Gauss proved that the number of sides of constructible polygons had to be of a certain form involving Fermat primes‚ corresponding to the so-called Trigonometry Angles. Although constructions for the regular triangle‚ square‚ pentagon‚ and their derivatives had been given by Euclid‚ constructions based on the Fermat primes were unknown to the ancients. The first explicit construction
