In mathematics, a monotonic function (or monotone function) is a function between ordered sets that preserves or reverses the given order. This concept...

equation relates the pair correlation function to the direct correlation function. The direct correlation function is only used in connection with the OZ...

analytic function is a function that is locally given by a convergent power series. There exist both real analytic functions and complex analytic functions. Functions...

Direct costs, in accounting, are costs directly accountable to a cost object (such as a particular project, facility, function, or product). The equivalent...

male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization...

standard sea level values. It so happens that the speed of sound is a direct function of temperature, so instead of a standard temperature, we can define...

{\displaystyle \circ } takes two functions, f {\displaystyle f} and g {\displaystyle g} , and returns a new function h ( x ) := ( g ∘ f ) ( x ) = g (...

(1969). In this earlier model, supply (specifically labor supply) is a direct function of real wages: more work will be done when real wages are high and...

generating function is a representation of an infinite sequence of numbers as the coefficients of a formal power series. Generating functions are often...

in Java when J/Direct was designed, Microsoft used a special syntax in Java comments. For example, to declare the GetSysColor function in the User32 API:...

continuation function is represented as a parameter named "k": In the CPS versions, the primitives used, like +& and *& are themselves CPS, not direct style...

direct.h is a C/C++ header file provided by Microsoft Windows, which contains functions for manipulating file system directories. Some POSIX functions...

In mathematics, theta functions are special functions of several complex variables. They show up in many topics, including Abelian varieties, moduli spaces...

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists...

a continuous function is a function such that a small variation of the argument induces a small variation of the value of the function. This implies...

Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through...
