Field of fractions
Every integral domain can be embedded in a field (see proof below). That is, using concepts from set theory, given an arbitrary integral domain (such as the integers), one can construct a field that contains -
Math Wiki
Welcome to the Math Wiki. As Wikipedia administrators are so fond of saying: "Wikipedia is not a textbook". Math Wiki, on the other hand, is a textbook. We are currently working on 1,240 articles -
Wedge product
The Wedge product is the multiplication operation in exterior algebra. The wedge product is always antisymmetric, associative, and anti-commutative. The result of the wedge product is known as a bivector; in (that is, three -
Tau (constant)
The Greek letter τ, (tau) is a suggested symbol for the circle constant representing the ratio between circumference and radius. The constant is equal to (2 times pi), and approximately. While there are infinitely many -
Pi (constant)
The mathematical constant π (Greek pi) is commonly used in mathematics. It is also known as Archimedes' constant. Pi is an irrational number. Furthermore, it is a transcendental number. -
Brahmagupta
Brahmagupta ( listen (help·info)) (598–668) was an Indian mathematician and an astronomer. Brahmagupta, whose father was Jisnugupta, wrote important works on mathematics and astronomy. In particular he wrote Brahmasphutasiddhanta (The Opening of the Universe -
Non-Euclidean geometry
In mathematics, non-Euclidean geometry describes hyperbolic and elliptic geometry, which are contrasted with Euclidean geometry. The essential difference between Euclidean and non-Euclidean geometry is the nature of parallel lines. Euclid's fifth postulate -

History of mathematics
The area of study known as the history of mathematics is primarily an investigation into the origin of discoveries in mathematics and, to a lesser extent, an investigation into the standard mathematical methods and notation -
Ordinal Number
This article is about the mathematical concept. For number words denoting a position in a sequence ("first", "second", "third", etc.), see Ordinal number (linguistics). In set theory, an ordinal number, or just ordinal, is the -
Hexadecimal
Template:Numeral systems In mathematics and computer science, hexadecimal (also base Template:Num, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the -

Binomial coefficient
In mathematics, the binomial coefficient is the coefficient of the term in the polynomial expansion of the binomial power. In combinatorics, is interpreted as the number of -element subsets (the -combinations) of an -element set -
History of calculus
Calculating volumes and areas, the basic function of integral calculus, can be traced back to the Moscow papyrus (c. 1820 BC), in which an Egyptian mathematician successfully calculated the volume of a pyramidal frustum. Greek -
Law of cosines
This article is about the law of cosines in Euclidean geometry. For the corresponding theorem in spherical geometry, see law of cosines (spherical). For the corresponding theorem in hyperbolic geometry, see law of cosines (hyperbolic -
Sphere
A sphere (from Greek σφαίρα — sphaira, "globe, ball," ) is perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is -
Statistics
For MathWiki statistics, see Special:Statistics and Special:WikiStats. Statistics is a broad mathematical discipline which studies ways to collect, summarize, and draw conclusions from data. It is applicable to a wide variety of academic -
Polygon
In geometry, a polygon is a plane figure bounded by a finite sequence of line segments, a two-dimensional polytope. The line segments that make up the polygon are called sides; their intersections are called -
Icosahedron
In geometry, an icosahedron (Greek: eikosaedron, from eikosi twenty+ hedron seat;/ˌaɪ.kəʊ.sə.ˈhi.dɹən/; plural: -drons, -dra/-dɹə/) is any polyhedron having 20 faces, but usually a regular icosahedron is implied, which has -

Orthogonal projection
For the orthographic projection as a map projection, see Orthographic projection in cartography. Template:Views Orthographic projection (or orthogonal projection) is a means of representing a three-dimensional object in two dimensions. It is a -
Dodecahedron
A dodecahedron (Greek δωδεκάεδρον, from δώδεκα'twelve'+ εδρον'base','seat' or'face') is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid composed of twelve regular pentagonal faces, with -
Equilateral triangle
In geometry, an equilateral triangle is a triangle in which all three sides are equal. In traditional or Euclidean geometry, equilateral triangles are also equiangular; that is, all three internal angles are also congruent to -
Ellipsoid
An ellipsoid is a type of quadric surface that is a higher dimensional analogue of an ellipse. The equation of a standard axis-aligned ellipsoid body in an xyz-Cartesian coordinate system is where ax -
Boolean logic
Boolean logic is a complete system for logical operations. It was named after George Boole, an English mathematician at University College Cork who first defined an algebraic system of logic in the mid 19th century
