Approximation theory — In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby. Note that what is meant by best and simpler will depend on … Wikipedia
Approximation — An approximation (represented by the symbol ≈) is an inexact representation of something that is still close enough to be useful. Although approximation is most often applied to numbers, it is also frequently applied to such things as… … Wikipedia
Sign (linguistics) — There are many models of the linguistic sign (see also sign (semiotics)). A classic model is the one by the Swiss linguist Ferdinand de Saussure. According to him, language is made up of signs and every sign has two sides: the signifier (French… … Wikipedia
Sign function — In mathematics, the sign function is a mathematical function that extracts the sign of a real number. To avoid confusion with the sine function, this function is often called the signum function (after the Latin form of sign ).In mathematical… … Wikipedia

Plus-minus sign — For other uses, see plus minus (disambiguation). ± The plus minus sign (±) is a mathematical symbol commonly used either to indicate the precision of an approximation, or to indicate a value that can be of either sign. The sign is normally… … Wikipedia
Stirling's approximation — In mathematics, Stirling s approximation (or Stirling s formula) is an approximation for large factorials. It is named in honour of James Stirling.The formula is written as:n! approx sqrt{2pi n}, left(frac{n}{e} ight)^{n}.Roughly, this means that … Wikipedia
Boussinesq approximation (buoyancy) — In fluid dynamics, the Boussinesq approximation (named for Joseph Valentin Boussinesq) is used in the field of buoyancy driven flow (also known as natural convection). It states that density differences are sufficiently small to be neglected,… … Wikipedia

Spouge's approximation — In mathematics, Spouge s approximation is a formula for the gamma function due to John L. Spouge. The formula is a modification of Stirling s approximation, and has the form:Gamma(z+1) = (z+a)^{z+1/2} e^{ (z+a)} left [ c 0 + sum {k=1}^{a 1}… … Wikipedia
