Function \Func"tion\, noun [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; performance. "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.

6. (Eccl.) A religious ceremony, esp. one particularly impressive and elaborate.

Every solemn 'function' performed with the requirements of the liturgy. --Card. Wiseman. [Webster 1913 Suppl.]

7. 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. [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 ^{-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 the __FCC__ website, "The Telecommunications Act of 1996 is the first major overhaul of telecommunications law in almost 62 years. The goal of this new law is to let anyone enter any communications business -- to let any communications business compete in any market against any other."

I am a communications business and I want to compete in the **C-SPAN HD**, **C-SPAN2 HD** and **C-SPAN3 HD** online commentary marketplace. **Comcast** is using it's monopoly position as my cable provider to prevent me from having access to **C-SPAN2 HD** and **C-SPAN3 HD**. Therefore, I am unable to compete in the **HD** **Congressional Commentary** marketplace. This is bad for **DEMOCRACY** and it is bad for the **INDEPENDENT JOURNALISTS** in **Comcast**'s service area. This reduces diversity of opinion in the **Congressional Commentary** marketplace and leads to the American citizens getting their news only from **official sources**, such as the major broadcast networks, cable networks and movie companies such as the **NBC** companies.
