FUNC'TION, n. [L. functio, from fungor, to perform.] 1. In a general sense, the doing, executing or performing of any thing; discharge; performance; as the function of a calling or office. More generally, 2. Office or employment, or any duty or business belonging to a particular station or character, or required of a person in the station or character. Thus we speak of the functions of a chancellor, judge or bishop; the functions of a parent or guardian. 3. Trade; occupation. [Less proper.] 4. The office of any particular part of animal bodies; the peculiar or appropriate action of a member or part of the body, by which the animal economy is carried on. Thus we speak of the functions of the brain and nerves, of the heart, of the liver, of the muscles, etc. 5. Power; faculty, animal or intellectual. As the mind opens, and its functions spread. 6. In mathematics, the function of a variable quantity, is any algebraic expression into which that quantity enters, mixed with other quantities that have invariable values.
n 1: (mathematics) a mathematical relation such that each element of a given set (the domain of the function) is associated with an element of another set (the range of the function) [syn: function, mathematical function, singlevalued function, map, mapping] 2: what something is used for; "the function of an auger is to bore holes"; "ballet is beautiful but what use is it?"

In mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another (the dependent variable), which changes along with it. Most functions are numerical; that is, a numerical input value is associated with a single numerical output value. The formula , for example, assigns to each positive real number the area of a circle with a radius of that length. The symbols and are typically used for functions of the independent variable . A multivariable function such as is a rule for deriving a single numerical value from more than one input value. A periodic function repeats values over fixed intervals. If for any value of is a periodic function with a period of length (a constant). The trigonometric functions are periodic. See also density function, exponential function, hyperbolic function, inverse function, transcendental function.

Function Func"tion, n. 1. (Eccl.) A religious ceremony, esp. one particularly impressive and elaborate. Every solemn `function' performed with the requirements of the liturgy. Card. Wiseman. 2. A public or social ceremony or gathering; a festivity or entertainment, esp. one somewhat formal. This function, which is our chief social event. W. D. Howells.
Fluent Flu"ent, n. 1. A current of water; a stream. [Obs.] 2. [Cf. F. fluente.] (Math.) A variable quantity, considered as increasing or diminishing;  called, in the modern calculus, the function or integral.
Function Func"tion, n. [L. functio, fr. fungi to perform, execute, akin to Skr. bhuj to enjoy, have the use of: cf. F. fonction. Cf. Defunct.] 1. The act of executing or performing any duty, office, or calling; per formance. ``In the function of his public calling.'' Swift. 2. (Physiol.) The appropriate action of any special organ or part of an animal or vegetable organism; as, the function of the heart or the limbs; the function of leaves, sap, roots, etc.; life is the sum of the functions of the various organs and parts of the body. 3. The natural or assigned action of any power or faculty, as of the soul, or of the intellect; the exertion of an energy of some determinate kind. As the mind opens, and its functions spread. Pope. 4. The course of action which peculiarly pertains to any public officer in church or state; the activity appropriate to any business or profession. Tradesmen . . . going about their functions. Shak. The malady which made him incapable of performing his regal functions. Macaulay. 5. (Math.) A quantity so connected with another quantity, that if any alteration be made in the latter there will be a consequent alteration in the former. Each quantity is said to be a function of the other. Thus, the circumference of a circle is a function of the diameter. If x be a symbol to which different numerical values can be assigned, such expressions as x^2, 3^x, Log. x, and Sin. x, are all functions of x. Algebraic function, a quantity whose connection with the variable is expressed by an equation that involves only the algebraic operations of addition, subtraction, multiplication, division, raising to a given power, and extracting a given root;  opposed to transcendental function. Arbitrary function. See under Arbitrary. Calculus of functions. See under Calculus. Carnot's function (Thermodynamics), a relation between the amount of heat given off by a source of heat, and the work which can be done by it. It is approximately equal to the mechanical equivalent of the thermal unit divided by the number expressing the temperature in degrees of the air thermometer, reckoned from its zero of expansion. Circular functions. See Inverse trigonometrical functions (below).  Continuous function, a quantity that has no interruption in the continuity of its real values, as the variable changes between any specified limits. Discontinuous function. See under Discontinuous. Elliptic functions, a large and important class of functions, so called because one of the forms expresses the relation of the arc of an ellipse to the straight lines connected therewith. Explicit function, a quantity directly expressed in terms of the independently varying quantity; thus, in the equations y = 6x^2, y = 10 x^3, the quantity y is an explicit function of x. Implicit function, a quantity whose relation to the variable is expressed indirectly by an equation; thus, y in the equation x^2 + y^2 = 100 is an implicit function of x. Inverse trigonometrical functions, or Circular function, the lengths of arcs relative to the sines, tangents, etc. Thus, AB is the arc whose sine is BD, and (if the length of BD is x) is written sin ^1x, and so of the other lines. See Trigonometrical function (below). Other transcendental functions are the exponential functions, the elliptic functions, the gamma functions, the theta functions, etc. Onevalued function, a quantity that has one, and only one, value for each value of the variable.  Transcendental functions, a quantity whose connection with the variable cannot be expressed by algebraic operations; thus, y in the equation y = 10^x is a transcendental function of x. See Algebraic function (above).  Trigonometrical function, a quantity whose relation to the variable is the same as that of a certain straight line drawn in a circle whose radius is unity, to the length of a corresponding are of the circle. Let AB be an arc in a circle, whose radius OA is unity let AC be a quadrant, and let OC, DB, and AF be drawnpependicular to OA, and EB and CG parallel to OA, and let OB be produced to G and F. E Then BD is the sine of the arc AB; OD or EB is the cosine, AF is the tangent, CG is the cotangent, OF is the secant OG is the cosecant, AD is the versed sine, and CE is the coversed sine of the are AB. If the length of AB be represented by x (OA being unity) then the lengths of Functions. these lines (OA being unity) are the trigonometrical functions of x, and are written sin x, cos x, tan x (or tang x), cot x, sec x, cosec x, versin x, coversin x. These quantities are also considered as functions of the angle BOA.
