47 Other Indian sources by about 150 BC treat π as.1622. 48 Polygon approximation era π can be estimated by computing the perimeters of circumscribed and inscribed polygons. The first recorded algorithm for rigorously calculating the value of π was a geometrical approach using polygons, devised around 250 BC by the Greek mathematician Archimedes. 49 This polygonal algorithm dominated for over 1,000 years, and as a result π is sometimes referred to as "Archimedes' constant". 50 Archimedes computed upper and lower bounds of π by drawing a regular hexagon inside and outside a circle, and successively doubling the number of sides until he reached a 96-sided regular polygon. By calculating the perimeters of these polygons, he proved that 223/71 π 22/7 (that.1408.1429). 51 Archimedes' upper bound of 22/7 may have led to a widespread popular belief that π is equal to 22/7.

There are n different complex numbers z satisfying z n 1, and these are called the " n -th roots of unity ". 39 They are given by this formula: e2pi ik/nqquad (k0,1,2,dots, n-1). History main article: Approximations of π see also: Chronology of computation of π antiquity The best-known approximations to π dating before the common Era were accurate to two decimal places; this was improved upon in Chinese mathematics in particular by the mid-first millennium,. After this, no further progress was made until the late medieval period. Some Egyptologists 40 have claimed that the ancient Egyptians used an approximation of π as 22/7 from as early as the Old Kingdom. 41 This claim writing has met with skepticism. The earliest written approximations of π are found in Egypt and Babylon, both within one percent of the true value. In Babylon, a clay tablet dated bc has a geometrical statement that, by implication, treats π as 25/8.125. 46 essay In Egypt, the Rhind Papyrus, dated around 1650 BC but copied from a document dated to 1850 bc, has a formula for the area of a circle that treats π as (16/9)2.1605. 46 Astronomical calculations in the Shatapatha Brahmana (ca. 4th century bc) use a fractional approximation of 339/108.139 (an accuracy of 9104).

Although the simple continued fraction for π hibernation (shown above) also does not exhibit any other obvious pattern, 31 mathematicians have discovered several generalized continued fractions that do, such as: 32 π displaystyle beginalignedpi textstyle cfrac 41textstyle cfrac 122textstyle cfrac 322textstyle cfrac 522textstyle cfrac 722textstyle cfrac. 30 (List is selected terms from A063674 and A063673.) Digits : The first 50 decimal digits are. 33 (see a000796 ) Digits in other number systems The first 48 binary ( base 2) digits (called bits ) are. (see a004601 ) The first 20 digits in hexadecimal (base 16) are.243F6A8885A308D31319. 34 (see a062964 ) The first five sexagesimal (base 60) digits are 3;8,29,44,0,47 35 (see a060707 ) Complex numbers and Euler's identity Any complex number, say z, can be expressed using a pair of real numbers. In the polar coordinate system, one number ( radius or r ) is used to represent z 's distance from the origin of the complex plane and the other (angle or φ) to represent a counter-clockwise rotation from the positive real line as follows:. The frequent appearance of π in complex analysis can be related to the behavior of the exponential function of a complex variable, described by euler's formula : 37 eiφcosφisinφ, displaystyle eivarphi cos varphi isin varphi, where the constant e is the base of the natural. This formula establishes a correspondence between imaginary powers of e and points on the unit circle centered at the origin of the complex plane. Setting φ π in Euler's formula results in Euler's identity, celebrated by mathematicians because it contains the five most important mathematical constants: 37 38 eiπ10.displaystyle eipi.

27 Squaring a circle was one of the important geometry problems of the classical antiquity. 28 Amateur mathematicians in modern times have sometimes attempted to square the circle and sometimes claim success despite the fact that it is mathematically impossible. 29 Continued fractions like all irrational numbers, π cannot be represented as a common fraction (also known as a simple or vulgar fraction by the very definition of "irrational number" (that is, "not a rational number. But every irrational number, including π, can be represented by an infinite series of nested fractions, called a continued fraction : π displaystyle pi 3textstyle cfrac 17textstyle cfrac 115textstyle cfrac 11textstyle cfrac 1292textstyle cfrac 11textstyle cfrac 11textstyle cfrac 11ddots Truncating the continued fraction at any. These numbers are among the most well-known and widely used historical approximations of the constant. Each approximation surgery generated in this way is a best rational approximation; that is, each is closer to π than any other fraction with the same or a smaller denominator. 30 Because π is known to be transcendental, it is by definition not algebraic and so cannot be a quadratic irrational. Therefore, π cannot have a periodic summary continued fraction.

22 Since the advent of computers, a large number of digits of π have been available on which to perform statistical analysis. Yasumasa kanada has performed detailed statistical analyses on the decimal digits of π and found them consistent with normality; for example, the frequencies of the ten digits 0 to 9 were subjected to statistical significance tests, and no evidence of a pattern was found. 23 Any random sequence of digits contains arbitrarily long subsequences that appear non-random, by the infinite monkey theorem. Thus, because the sequence of π's digits passes statistical tests for randomness, it contains some sequences of digits that may appear non-random, such as a sequence of six consecutive 9s that begins at the 762nd decimal place of the decimal representation. 24 This is also called the "Feynman point" in mathematical folklore, after Richard feynman, although no connection to feynman is known. Transcendence In addition to being irrational, more strongly π is a transcendental number, which means that it is not the solution of any non-constant polynomial equation with rational coefficients, such as x 5/120 x 3/6. 25 26 The transcendence of π has two important consequences: First, π cannot be expressed using any finite combination of rational numbers and square roots or n -th roots such as 331. Second, since no transcendental number can be constructed with compass and straightedge, it is not possible to " square the circle ". In other words, it is impossible to construct, using compass and straightedge alone, a square whose area is exactly equal to the area of a given circle.

11 17 A more abstract variation on the same idea, making use of sophisticated mathematical concepts of topology and algebra, is the following theorem: 18 there is a key unique ( up to automorphism ) continuous isomorphism from the group R / z of real numbers. The number π is then defined as half the magnitude of the derivative of this homomorphism. 19 A circle encloses the largest area that can be attained within a given perimeter. Thus the number π is also characterized as the best constant in the isoperimetric inequality (times one-fourth). There are many other, closely related, ways in which π appears as an eigenvalue of some geometrical or physical process; see below.

Irrationality and normality π is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 restaurant are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value). 20 Because π is irrational, it has an infinite number of digits in its decimal representation, and it does not settle into an infinitely repeating pattern of digits. There are several proofs that π is irrational ; they generally require calculus and rely on the reductio ad absurdum technique. The degree to which π can be approximated by rational numbers (called the irrationality measure ) is not precisely known; estimates have established that the irrationality measure is larger than the measure of e or ln(2) but smaller than the measure of liouville numbers. 21 The digits of π have no apparent pattern and have passed tests for statistical randomness, including tests for normality ; a number of infinite length is called normal when all possible sequences of digits (of any given length) appear equally often. 22 The conjecture that π is normal has not been proven or disproven.

This definition of π implicitly makes use of flat (Euclidean) geometry ; although the notion of a circle can be extended to any curved (non-Euclidean) geometry, these new circles will no longer satisfy the formula π c /. 9 Here, the circumference of a circle is the arc length around the perimeter of the circle, a quantity which can be formally defined independently of geometry using limits, a concept in calculus. 10 For example, one may compute directly the arc length of the top half of the unit circle given in Cartesian coordinates by x 2 y 2 1, as the integral : 11 π11dx1x2.displaystyle pi int _-11frac dxsqrt 1-x2. An integral such as this was adopted as the definition of π by karl weierstrass, who defined it directly as an integral in 1841. 12 Definitions of π such as these that rely on a notion of circumference, and hence implicitly on concepts of the integral calculus, are no longer common in the literature.

Remmert (1991) explains that this is because in many modern treatments of calculus, differential calculus typically precedes integral calculus in the university curriculum, so it is desirable to have a definition of π that does not rely on the latter. One such definition, due to richard Baltzer, 13 and popularized by Edmund Landau, 14 is the following: π is twice the smallest positive number at which the cosine function equals. 9 11 15 The cosine can be defined independently of geometry as a power series, 16 or as the solution of a differential equation. 15 In a similar spirit, π can be defined instead using properties of the complex exponential, exp( z of a complex variable. Like the cosine, the complex exponential can be defined in one of several ways. The set of complex numbers at which exp( z ) is equal to one is then an (imaginary) arithmetic progression of the form: dots,-2pi i,0,2pi i,4pi i, dots 2pi kimid kin mathbb z and there is a unique positive real number π with this property.

7 In English, π is business pronounced as "pie" ( /paɪ/, py ). 8 In mathematical use, the lowercase letter π (or π in sans-serif font) is distinguished from its capitalized and enlarged counterpart, which denotes a product of a sequence, analogous to how denotes summation. The choice of the symbol π is discussed in the section Adoption of the symbol. Definition The circumference of a circle is slightly more than three times as long as its diameter. The exact ratio is called. Π is commonly defined as the ratio of a circle 's circumference c to its diameter d : business 9 πCddisplaystyle pi frac Cd The ratio c / d is constant, regardless of the circle's size. For example, if a circle has twice the diameter of another circle it will also have twice the circumference, preserving the ratio c /.

4 Practically all scientific applications require no more than a few hundred digits of π, and many substantially fewer, so the primary motivation for these computations is the quest to find more efficient algorithms for calculating lengthy numeric series, as well as the desire. 5 6 The extensive calculations involved have also been used to test supercomputers and high-precision multiplication algorithms. Because its most elementary definition relates to the circle, π is found in many formulae in trigonometry and geometry, especially those concerning circles, ellipses, and spheres. In more modern mathematical analysis, the number is instead defined using the spectral properties of the real number system, as an eigenvalue or a period, without any reference to geometry. It appears therefore in areas of mathematics and the sciences having little to do with the geometry of circles, such as number theory and statistics, as well as in almost all areas of physics. The ubiquity of π makes it one of the most widely known mathematical constants both inside and outside the scientific community. Several books devoted to π have been published, and record-setting calculations of the digits of π often result in news headlines. Attempts to memorize the value of π with increasing precision have led to records of over 70,000 digits. Contents Fundamentals Name The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter π, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference.

; that is, a number that is not the root of any non-zero polynomial having rational coefficients. This transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge. Ancient civilizations required fairly accurate computed values for π for practical reasons, including the Egyptians and Babylonians. Around 250 bc the Greek mathematician Archimedes created an algorithm for calculating. It was approximated to seven digits, using geometrical techniques, in Chinese mathematics, and to about five digits in Indian mathematics in the 5th century. The historically first exact formula for π, based on infinite series, was not available until a millennium later, when in the 14th century the madhavaleibniz series was discovered in Indian mathematics. 2 3 In the 20th and 21st centuries, mathematicians and computer scientists discovered new approaches that, when combined with increasing computational power, extended the decimal representation of π to many trillions of digits after the decimal point.

For the Greek letter, see. For other uses, see, pi (disambiguation). The number π ( /paɪ/ ) is a report mathematical constant. Originally defined as the ratio of a circle 's circumference to its diameter, it now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics. It is approximately equal.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as " pi ". It is also called, archimedes constant. Being an irrational number, π cannot be expressed exactly as a common 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.
