1 Scope

This section provides the basic concepts of linear algebra and mathematical terms of electrical, electronic and telecommunications fields, and a clear distinction between the mathematical concepts Different physical concepts, even if some of the terms in these two disciplines are used, the other part is about the function of the term. Many mathematical term for Electrotechnical terminology, is not always self-explanatory or only one explanation. So the task here is to collect this Kind of mathematical concepts, according to their interrelated in a logical and sequential manner choreography terms be described. From the point of view of Terminology Look, the description is given in the definition, but are not very well defined mathematical sense. The main purpose here is to be able to distinguish between the concept and special. Therefore, do not be seen as part of the math textbook, but rather as a set of specialized terms. The term set forth in section IEC 60050 series of standards of the International Electrotechnical Vocabulary (IEV) to other parts of the existing term and coordinated. This section applies to the technical field of electrical, electronics and telecommunications.

3 Terms and Definitions

3.1 collection and calculation 102-01-01 Two objects a, b have the relationship between the nature of the following. ● reflexive. = Rao Rao; ● Symmetry. If Rao = Chou, the Chou = Rao; ● Transitive. If Rao = Chou and Chou = Ba, then Rao = Ba, where c is the third object; ● If Rao = Chou and R {u} is a statement about any u, then R {Rao} is true if and only if R {} Chou is true. Note. The two objects are equal denoted by Rao and Rao = Chou Chou, called Rao and Chou equal. 102-01-02 Some whole different objects, for any object, are clearly all or part of this, or do not belong to this plenary. Note 1. The collection is a fundamental concept in mathematics. Note 2. For a set of symbols and terminology see GB 3102.11-1993 2.4. 102-01-03 Given set of objects. Note. The mark indicates x0 ∈A object x is the element of the collection A, known x0 belongs to A. Mark x0 x0 A represented object is not an element of the set A, called x0 does not belong to A.
