  Domain (mathematics) - Wikipedia, the free encyclopedia
In mathematics, the domain of a function is the set of all input values to the function.
There are two distinct meanings in current mathematical usage for the notion of the domain of a partial function.
In complex analysis, a domain is an open connected subset of the complex numbers.

In Working mathematically students learn to move from consideration of multiple examples of true propositions to informal consideration of justification for general conjectures based on the examples.
Students develop simple mathematical models for familiar and unfamiliar situations based on the identification of characteristic conditions such as symmetry, invariance and constant rates of change.
They apply standard mathematical models and make predictions based on interpolation (working with what is already known) and extrapolation (working beyond what is already known) using known computations and established constructions.

 Computational Mathematics
Mathematical maturity and a broad knowledge of various areas in mathematics would be advantageous.
Domain decomposition methods (DDMs) were originated by Schwarz back in the 19th century (1870) as a way of solving boundary value problems on complicated geometries.
The aim of this course will be to give an introduction to the use of domain decomposition methods as preconditioning techniques to solve linear systems of equations arising from the discretisation of partial differential or boundary integral equations.

 Function domain   (Site not responding. Last check: 2007-10-13)
In mathematics, given a function f: A → B, the set A is called the domain, or domain of definition of f.
It is thus not a function on the set R of real numbers; R can't be its domain.
The domain of given function can be restricted to a subset.

 Ernst von Glasersfeld - An Exposition of Constructivism: Why some like it radical
To indicate that the theoretical infallibility of mathematical operations (in practice, mistakes may, of course, occur) cannot be claimed as proof that these operations give access to an ontological reality, I have compared this generation of certainty to the game of chess.
This is one of the reasons why mathematics teachers often insist (to the immense boredom of the students) on the exact documentation of the algorithm by means of which the result was obtained.
Similarly, there is no harm in speaking of knowledge, mathematical and other, as though it had ontological status and could be "objective" in that sense; as a way of speaking this is virtually inevitable in the social interactions of everyday life.

 Unique factorization domain   (Site not responding. Last check: 2007-10-13)
In mathematics, a unique factorization domain (UFD) is, roughly speaking, a ring in which every element can be uniquely written as a product of prime elements, analogous to the fundamental theorem of arithmetic for the integers.
Formally, a unique factorization domain is defined to be an integral domain R in which every non-zero non-unit[?] x of R can be written as a product of irreducible elements of R:
All principal ideal domains are UFD's; this includes the integers, all fields, all polynomial rings K[X] where K is a field, and the Gaussian integers Z[i].

 Mathematics - a new Domain for Datamining
One problem, of course, is the sheer amount of mathematical data available: in [hoffman:erdos] it is estimated that around 250,000 new theorems are proved and presented in journals every year.
Automated discovery in mathematics does not necessarily have to be based on the formal definitions of concepts and statements of conjectures.
Mathematical databases have the same problems as other scientific datasets: they are heterogeneous both internally and in relation to each other.

Another essential aim is to foster understanding of the intellectual and cultural pluralism of modern society as it is reflected in natural science and mathematics; behavioral, cultural, and social science; and literature and artistic expression.
The Core Curriculum is built on the assumption that the foundations of the general part of a student’s education are laid in secondary school.
To achieve the objectives of Domain I, students must demonstrate knowledge of higher mathematics sufficient to understand the basis of mathematical reasoning, and knowledge of the methods, intellectual approaches, social significance, and history of the physical and natural sciences.

 S.O.S. Mathematics CyberBoard :: View topic - Domain Question for composite functions
This conclusion works, assuming the domain of g(x) can properly be defined so that it results in no values in the range of g(x) such that, when the values of the range of g(x) are defined as the domain of f(x), f(x) operates to, for example, divide by zero.
A value that, in the domain of g(x), corresponds to a range value for g(x) which is in the domain of f(x) is in the domain of the composite, even though it is outside the domain values of f(x).
But I recall from somewhere that one must exclude from the domain of a composite function any value which is excluded from the domain of any of the functions of which it is composed.

 A Constructivist Approach to Infusing Learning Domain and Multiple Intelligence Theories into Mathematics Instruction   (Site not responding. Last check: 2007-10-13)
Add to the mix a requirement for students to complete at least one course in mathematics during the first semester and the conditions are set for potential academic disaster.
To mitigate against this prospect, a father son team, the father a professor of education and the son a professor of mathematics, pools their discipline expertise in order to create opportunities for successful learning experiences in college mathematics.
The team applies pedagogical theory to the content of college algebra with a focus on providing low stress, high achievement experiences for students from any population, but especially for students who are historically underrepresented among the ranks of college students.

 Coincidence point - tScholars.com   (Site not responding. Last check: 2007-10-13)
In mathematics, a coincidence point (or simply coincidence) of two mappings is a point in their domain having the same image point under both mappings.
Notable among them, in the setting of manifolds, is the Lefschetz coincidence theorem, which is typically known only in its special case formulation for fixed points.
Coincidence points, like fixed points, are today studied using many tools from mathematical analysis and topology.

 Modulus of continuity -   (Site not responding. Last check: 2007-10-13)
In mathematics, the modulus of continuity is a precise way to measure the smoothness of a function.
It is used as a delicate tool in mathematical analysis, to discuss highly non-smooth functions, which nonetheless enjoy some (very generalized) kind of smoothness.
Similar but less refined notions such as Lipschitz continuity and Hölder class are subsumed by the explicit use of the modulus of continuity.

Posted: Tue, 7 Jun 2005 20:01:30 GMT Post subject: This is meant as a challenge to the tutors and others.
To find the domain of y, we must determine the values of x for which y is defined (i.e., nothing funny happens, such as dividing by 0).
First, the expression under the square root symbol must be positive (it can't be negative, for otherwise we would be taking the square root of a negative number, and it can't be 0, for otherwise we would have a division by 0 error).

 Interface, Instructional Approach, and Domain Learning with a Mathematics Problem-Solving Environment - Storming Media
Abstract: We conceptualize Computer-Based Instruction (CBI) as involving both a primary task, learning to use a particular domain, and a secondary task, learning to use instructional approach embodied in a computer system and to manipulate its interface.
We argue that the complexity and compatibility of the instructional approach and the interface separately and interactively influence the ease with which students are able to learn the subject matter.
We also describe an experimental methodology for dissociating and measuring the separate relative effect on learning of using a CBI system for mathematics word problems.
