Função afim e aplicações

Abstract

The knowledge about the emergence and development of mathematical concepts is a tool of essential importance for the teacher in the elaboration of a mathematical language that provides a greater understanding on the part of the students. There is a notorious difficulty of the students in relation to the concept of function, either by the rigor of formalism or by the range of definitions about the theme. In this work, the applications of the related function were explored, establishing connections with other themes, aiming to make the content understandable and meaningful for the student. The textbook used presents the content in a dynamic and illustrated way, bringing applications of theory, exercises of varying levels of difficulty. The methodology we suggest to the teacher is to work the applications through some tools, such as the projector or computer. This work gives a brief retrospective about the evolution of this concept, as well as analysis of annotations of content on screen.
