1approximating function — artutinė funkcija statusas T sritis fizika atitikmenys: angl. approximating function; approximation function vok. approximierende Funktion, f; Näherungsfunktion, f rus. аппроксимирующая функция, f; приближённая функция, f pranc. fonction… …
2Function approximation — The need for function approximations arises in many branches of applied mathematics, and computer science in particular. In general, a function approximation problem asks us to select a function among a well defined class that closely matches (… …
3Radial basis function — A radial basis function (RBF) is a real valued function whose value depends only on the distance from the origin, so that phi(mathbf{x}) = phi(||mathbf{x}||); or alternatively on the distance from some other point c , called a center , so that… …
4Average order of an arithmetic function — In number theory, the average order of an arithmetic function is some simpler or better understood function which takes the same values on average .Let f be an arithmetic function. We say that the average order of f is g if : sum {n le x} f(n)… …
5Normal order of an arithmetic function — In number theory, the normal order of an arithmetic function is some simpler or better understood function which usually takes the same or closely approximate values. Let ƒ be a function on the natural numbers. We say that the normal order of ƒ… …

7Auxiliary function — In mathematics, auxiliary functions are an important construction in transcendental number theory. They are functions which appear in most proofs in this area of mathematics and that have specific, desirable properties, such as taking the value… …
8Dirac delta function — Schematic representation of the Dirac delta function by a line surmounted by an arrow. The height of the arrow is usually used to specify the value of any multiplicative constant, which will give the area under the function. The other convention… …
9Dirichlet eta function — For the modular form see Dedekind eta function. Dirichlet eta function η(s) in the complex plane. The color of a point s encodes the value of η(s). Strong colors denote values close to zero and hue encodes the value s argumen …
10Renal function — Diagram showing the basic physiologic mechanisms of the kidney Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid …
