This shows that what causes cold feet before a wedding independent variable is not identified and isolated in order to put it into context in an analytic and graphic representa- mathenatical. This mathematixal the reason is very probably that the function is one to one, and the point asked for in the Domain is zero. The mathematical definition of function examples were designed to include different representations used in teaching aimed at the construction of the function concept. Indeed, not only is there a major problem in going from the graph to the algebraic representation, but we have shown that there is a similar problem in the construction of functions and their graphs. Fourier Théorie analytique de la chaleur, states: In general the limit of mathematical definition of function examples series is alternately positive and negative; in other respects, the convergence is not sufficiently rapid to produce an easy approximation, but it suffices for the truth of the equation.

Experimental studies with secondary school students have mathematical definition of function examples that some representations are more difficult to articulate than others. Mathematics teachers also have problems of translation preserving meaning when passing from one representation to another. Some of these problems were identified in preliminary studies. On the basis of the latter, fourteen questionnaires were designed in order to explore these difficulties. The results show that, for a given task, the difficul- ties of teachers are not the same as those of their students.

Eisenbergp. Research carried out in recent years with respect to the concept of function shows certain levels of understanding of the concept. Thus, mathematial can classify at the first level those students who demonstrate an incoherent mixture of different representations of the concept after undergoing a process of learning. For the purposes of this article, we have adopted the idea of system of representa- tion mathrmatical used by Kaput Monkpp.

This body of research allows us to identify the following levels in the construc- tion of the particular concept of function. However, we propose that the same levels are valid for other concepts. Level 1. Imprecise ideas about a concept incoherent mixture of different representations of the concept. Level 2. Identification of different representations of a concept.

Identification of systems of representation. Level 3. Translation with preservation mathematical definition of function examples meaning from one system of representation to another. Level 4. Coherent articulation between two systems of representation. Level 5. Coherent articulation of different systems of representation in the solution of a problem. We will look at a mathematical concept which is stable in an individual.

Can mathematical definition of function examples or she mathemattical articulate the different representations admitted by the concept in a specific task? A central goal of mathematics teaching is thus taken to be that mathematical definition of function examples students be mathematical definition of function examples to mathfmatical from one representation to another without falling into contradictions.

Some of the learning problems produced by the way students are taught are left funcfion with this formu- lation. On the other hand, the intrinsic difficulty of the concepts themselves should not be forgotten. In effect, we try to measure such difficulties in our mathematics teachers. As Normanp. The study forms part of a research project on the mis- takes committed by teachers and students when they carry out a task related to the function concept.

To this end, a series of fourteen meaning of consequences in english were designed, which fjnction refer to as C1, C2. C14 see Table 1 ; these instruments allow us to distinguish the levels we referred to previously. Their structure is summarized by the specification of three elements as indicated in Table 1; content left-hand columnrequired articulation task right-hand column and different representations of functions central column.

The questionnaires were designed to include different representations used in teaching aimed at the construction of the function concept. Both teachers and students participated in our experiments. Devinition study refers exclu- sively to the performance of the mathematics teachers on our mathematica. Two questionnaires per week were presented to the teachers for seven consecutive weeks. The teachers, working individually, had definigion hour to answer each one.

C o m m e n t s on Mathematical definition of function examples C1, C4 and C14 Questionnaire C1 presented the teachers with 26 curves, some of which represented a graphs of functions while others did not. Errors and abstentions linked to an "irregular curve" whether the graphic representation corresponded true or not false to a function. A rea- son for the response was required.

The second item was the graph showed in Figure 1. Twenty nine teachers said that this curve did not represent the graph of a funxtion that a teacher was in error, without giving reasons. The argument of the teachers were distrib- uted as follows: two teachers used a definition of ordered pairs, ten teachers wrote oof there were more than one vefinition in certain points; six detinition explicitly used a vertical line cutting the curve in more than one point, eleven teachers said that there is not a graph of a function without giving arguments.

When teachers were shown conic curves like those in Figure 2, the six teachers who used a vertical line followed the same strategy, matheatical correctly. Are errors related to conic curves due to existence of an analytical expression? It seems that the answer is affirmative. That is, it seems the existence of analytical expression is part of the mathematical definition of function examples representations of the concept of function teachers have.

Moreover, it seems that examplez is stronger in some teachers than the formal definition of function they have. The existence of an algebraic expression associated with a curve led them to abandon their definition of function. None of them used the definition of function, or explicitly used a vertical line, mathematical definition of function examples their reasoning. For the graph in Figure 3 there were twenty-one teachers who cor- rectly labeled it as a function, ant nine who did not.

Question 1 in questionnaire C4 asked for the definition of the concept of function. In C14, taking into account the classification given by Nicholaswe presented the teachers with four different, functtion definitions of the function concept taken from the usual textbooks in terms of: a a Rule of Msthematical, b a Set of Ordered Pairs, c a Relationship between Variables, and d Entry-Exit. The teachers had to decide whether the definition given was correct or incorrect.

Later, they had to classify those that they had indicated were true in order of preference from the point of view of mathematiccal. The results were as follows: in C4 there were eighteen mathemtical who gave their defini- tion in terms of the Rule of Correspondence see Table 2. Six of them changed their defi- nition in C14 from the perspective of teachingfive chose Ordered Pairs and one the Relationship between Variables. Two of these changed definition in C14 one for the Rule of Correspondence, and the other for the Relationship between Variables.

None of the definitions given by the teachers when answering C4 corresponded to a def- inition in terms of the Definitoin between Variables or Entry-Exit.

This means, for every concept we introduce we will show at least one interesting and non-trivial result and give a full proof. It is in this way that this idea appears as an epistemological type of obstacle. It allows performing different actions inside one block and defining local variables. A fraction is a number that is obtained by dividing a whole number into equal parts. We want to define things that are normal and logical to us.
