(programming) Programming in a style that, in lieu of assignment, uses procedure calls to bind variables to values, so that referential transparency is preserved.

(mathematics) A set functions that are analogues of the trigonometric functions for hyperbolic spaces. They can be derived from some arithmetic operations on the exponential function with base e and the inverse function, and was named after the corresponding similar trigonometric function.

(mathematics) A function, the result of the division of two exponential functions, that gives rise to the logistic curve.

(physics) a mathematical function that describes the behaviour of paramagnetic materials and the dielectric properties of insulators

(mathematics) a function of the generalized coordinates and velocities of a dynamic system from which Lagrange's equations may be derived

(mathematics) Any metric space whose elements are functions

(medicine) A branch of kinesiology that studies the configuration of limbs during the performance of a task.

(mathematics) A function that assigns a pair of vertices to each edge of a graph.

(mathematics) Any generalized function which is defined by its behavior under integration.

(mathematics) Any function of a real variable whose value increases (or is constant) as the variable increases.
