  Function \Func"tion\, n. [L. functio, fr. fungi to perform,

        [Webster 1913 Suppl.]
  
     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 (Thermo-dynamics), 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 functions,
        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.
  
     One-valued 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.

Din dicționarul The Free On-line Dictionary of Computing (27 SEP 03) :

  function
       
          1.  (Or "map", "mapping") If D and C are sets
          (the domain and codomain) then a function f from D to C,
          normally written "f : D -> C" is a subset of D x C such that:
       
          1. For each d in D there exists some c in C such that (d,c) is
          an element of f.  I.e. the function is defined for every
          element of D.
       
          2. For each d in D, c1 and c2 in C, if both (d,c1) and (d,c2)
          are elements of f then c1 = c2.  I.e. the function is uniquely
          defined for every element of D.
       
          See also image, inverse, partial function.
       
          2.  Computing usage derives from the mathematical
          term but is much less strict.  In programming (except in
          functional programming), a function may return different
          values each time it is called with the same argument values
          and may have side effects.
       
          A procedure is a function which returns no value but has
          only side-effects.  The C language, for example, has no
          procedures, only functions.  ANSI C even defines a type,
          void, for the result of a function that has no result.
       
          (1996-09-01)
       
       

Din dicționarul Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  FUNCTION, office. Properly, the occupation of an office; by the
  performance of its duties, the officer is said to fill his
  function. Dig. lib. 32, 1. 65, Sec. 1.
