Constant function information

In mathematics, a constant function is a function whose (output) value is the same for every input value. As a real-valued function of a real-valued argument...

intervals. Informally speaking, a step function is a piecewise constant function having only finitely many pieces. A function f : R → R {\displaystyle f\colon...

In mathematics, a locally constant function is a function from a topological space into a set with the property that around every point of its domain...

constant of integration, often denoted by C {\displaystyle C} (or c {\displaystyle c} ), is a constant term added to an antiderivative of a function f...

polynomial, and are generally non-constant functions. A coefficient is a constant coefficient when it is a constant function. For avoiding confusion, the coefficient...

domain. A nonzero constant P for which this is the case is called a period of the function. If there exists a least positive constant P with this property...

can be expressed as the ratio between two holomorphic functions (with the denominator not constant 0) defined on D: any pole must coincide with a zero of...

monotone are not invertible because they are constant on some interval (and therefore are not one-to-one). A function may be strictly monotonic over a limited...

zero). When the function is of only one variable, it is of the form f ( x ) = a x + b , {\displaystyle f(x)=ax+b,} where a and b are constants, often real...

1, the function is decreasing (as depicted for b = 1/2); this is often referred to as exponential decay. For b = 1, the function is constant. Euler's...

{\displaystyle c\in \mathbb {R} } , if f ( x ) {\displaystyle f(x)} is the constant function given by f ( x ) = c {\displaystyle f(x)=c} , then d f d x = 0 {\displaystyle...

called the Lipschitz constant of the function (and is related to the modulus of uniform continuity). For instance, every function that is defined on an...

(collisions). Hash functions rely on generating favourable probability distributions for their effectiveness, reducing access time to nearly constant. High table...

Constant elasticity of substitution (CES), in economics, is a property of some production functions and utility functions. Several economists have featured...

theory, a normalizing constant or normalizing factor is used to reduce any probability function to a probability density function with total probability...

Constant-function market makers (CFMM) are a paradigm in the design of trading venues where a trading function and a set of rules determine how liquidity...

They are the smallest class of partial functions that includes the constant, successor, and projection functions, and is closed under composition, primitive...

subdomain. Examples of functions with such piecewise properties are piecewise constant functions, piecewise linear functions (see the figure), piecewise...

real-valued function with a connected domain, the image is either an interval or a single value. In the latter case, the function is a constant function. The...
