  Quotient - Wikipedia, the free encyclopedia
In mathematics, a quotient is the end result of a division problem.
In more abstract branches of mathematics, the word quotient is often used to describe sets, spaces, or algebraic structures whose elements are the equivalence classes of some equivalence relation on another set, space, or algebraic structure.
Quotients also come up in certain tests, like the IQ test, which stands for intelligence quotient.

 Derivative
Velocity (instantaneous velocity; the concept of average velocity predates calculus) is the derivative (with repsect to time) of an object's position.
Jerk is the derivative (with respect to time) of an object's acceleration.
If the velocity of a car is given, as a function of time; then, the derivative of said function describes the acceleration of said car, as a function of time.

 Derivative - Wikipedia, the free encyclopedia
Arguably the most important application of calculus to physics is the concept of the "time derivative"—the rate of change over time—which is required for the precise definition of several important concepts.
Velocity (instantaneous velocity; the concept of average velocity predates calculus) is the derivative (with respect to time) of an object's position.
Acceleration is the derivative (with respect to time) of an object's velocity, that is, the second derivative (with respect to time) of an object's position.

 ATPM 9.03 - Roll Your Own: The Object of Programming
Yet another advantage of object oriented programming is the concept of inheritance, where a new object can inherit all of the properties and handlers of an existing object, can modify them as needed, or even overwrite them completely.
When a child object has a parent object, all of the properties, handlers, and any other code within the parent object are part of the child object.
However, a general rule when creating objects is to build code only for what you need for each object and when you need to expand on that code, create a new object that inherits from the first.

consists of all regular (strict, normal, etc.) epimorphisms, then the corresponding quotient objects are called regular (strict, normal, etc).
For example, in the category of topological spaces quotient spaces correspond to regular quotient objects.
The concept of a quotient object of an object in a category is dual to that of a subobject.

except that it rounds the argument or quotient of the arguments to the nearest integer.
In the case of a tie (the argument or quotient is exactly halfway between two integers), it rounds to the even integer.
may also be an integer in which case the new object is seeded from that integer; each different integer seed will result in a completely different sequence of random numbers.

Therefore the objects in mod D coincide, up to isomorphism, with the objects in* * mod C. Moreover, the maps in mod D are obtained via a calculus of fractions from the m* *aps in mod C; see [11, I.2.5].
We conclude that F is not a cohomological quotient funct* *or.
Moreover, The* *orem 4.4 implies that F is a cohomological quotient functor.

Arguably the most important application of calculus, to physics, is the concept of the "time derivative" -- the rate of change over time -- which is required for the precise definition of several important concepts.
For example, if an object's position p(t) = -16t2 + 16t + 32; then, the object's velocity is p'(t) = -32t + 16; the object's acceleration is p''(t) = -32; and the object's jerk is p'''(t) = 0.

 Reduction of nonlinear dynamic cintrol systems.   (Site not responding. Last check: 2007-10-23)
If two objects S1 and S2 are defined on the sets M1 and M2, respectively, then a morphism f of the object S1 into the object S2 is a mapping f from M1 to M2 that preserves the structure of a given kind (i.e., preserves the corresponding relationships between the elements of the sets).
The concept of a subobject results from our desire to construct correctly the restriction of an object S1 defined on a set M to a subset N of M. It is generally not possible to restrict an object S1 to an arbitrary set.
An object S2 defined on a subset N is called a subobject if the canonical injection of N to M is a morphism.

 RsaXli::ExtDiv
The ExtDiv member function divides the numerical value encapsulated by the presenting RsaXli object by the numerical value of the rOth object and places the quotient in the rQuo object and the remainder in the rRem object.
The identification of the most significant quotient digit is done just as it is done in long division by hand: the number of significant digits of the divisor is subtracted from the number of significant digits of the dividend to produce the (maximum) number of significant digits in the quotient.
The quotient digit is reliably underestimated by dividing the key digit of the current dividend by the quantity 1 plus the most-significant digit of the divisor.

 Metadata for Data Warehousing using Extended Relational Models
It is suitable as a concept of an object oriented meta model for OLAP-data, since it inherently uses the concept of object identifiers, a typology of different object types, such as: associations, characteristics, and kernel object types; and a meta model description on the relationships between the different types.
The use of quotient and nested relations in object oriented databases is relatively easy possible by defining the appropriate class-hierarchies for these relations together with their well defined operators.
Especially for MOLAP databases the complex objects of quotient relations and nested relations are highly suitable for performing roll-up and drill-down on the fly.

Thus all objects are cofibrant, f and f0 are cofibrations, Z = Y=X and Z0= Y 0=* *X0, g and g0 are quotient maps, and h and h0are connecting maps ffi.
Thus* *, in each case, the first map is a cofibration, the second map is a quotient map, and the third map is a connecting map as in (5.4).
Since maps in C between fibrant and cofibrant objects are homotopy classes of maps, the left square is homotopy commutative.

 glyf: worse was "better", but now "superior" - better now stuponfucious and we don't know what it was
Given the explicit task of upgrading a few simple objects (of the style present in the code from which the New Jersey example is taken) to a new and better representation, the Right Thing wins hands down.
It makes you think about what other objects need to be included in the representation in order for the evalled object to be considered "equivalent" to the original.
Someone changes something in a new release of Quotient and the object is now different than it was before and the persistence becomes broken.

The objects, on the other hand are 'complicated' in the sense of the many levels of abstraction and the great time and effort needed to 'construct' them in the mind of the student.
She finally employs a proceptual argument in order to indicate the flexibility in shifting from the process to the object aspects of a concept as a sign of mathematical maturity: this flexibility is a requirement for successful handling of tasks like finding the inverse of a compound element.
Normality is also confused with commutativity and the students' ignoring the condition of normality for the existence of the quotient group influences heavily their attempts to construct the cosets.

Lattice of Objects Inducing a Diversity of Sign Partitions But for the present I ought to say what I intend by this: Infinite diversity poses an obstacle to nominal thinking.
Well, one way to reduce the problem is to ignore the problematic domain of objects in toto, whether intentional or clear and present, and one way to get away with it is suggested by the very k-ptyches that we have staring at all this while.
Well, then, we would have a form-preserving copy of the object domain quite well in hand with the quotient object of the sign domain and the object domain should be a "world well wiled" out of mind.

That is, the amount of space traversed by an object divided by the amount of space traversed by my clock (Imagine a slider control – like on the front of a stereo.) gives a measure of a relative change in position.
