Différence finie — En mathématique, une différence finie est une expression de la forme f(x + b) − f(x + a). (où f est une fonction numérique) ; la même expression divisée par b − a s appelle un taux d accroissement (ou taux de… … Wikipédia en Français
Difference quotient — The primary vehicle of calculus and other higher mathematics is the function. Its input value is its argument, usually a point ( P ) expressible on a graph. The difference between two points, themselves, is known as their Delta (ΔP), as is the… … Wikipedia
Finite difference — A finite difference is a mathematical expression of the form f(x + b) − f(x + a). If a finite difference is divided by b − a, one gets a difference quotient. The approximation of derivatives by finite differences… … Wikipedia
Method ringing — (also known as scientific ringing) is a form of change ringing (the practice of ringing a series of mathematical permutations on tuned bells, rather than a melody). In method ringing, the ringers are guided from permutation to permutation by… … Wikipedia
