      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

            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 ^{-1}x, 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.

From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Function \Func"tion\, Functionate \Func"tion*ate\, v. i.
      To execute or perform a function; to transact one's regular
      or appointed business.

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   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.
