Desigualdade isoperimétrica: aspectos históricos e uma abordagem para o ensino médio.

Abstract

This dissertation aims to know the historical process of the emergence of mathematics and isoperimetric inequalities, as well as to present approaches of isoperimetric problems that can be used in high school. On order to achieve the objective of this research, bibliographical research was adopted as methodology. Despite the long existence of the study of the isoperimetric problem over time this is still the focus of many mathematicians. Many generalizations of isoperimetric inequalities in the most varied mathematical contexts are much studied in different areas of mathematical investigation. Ot is pertinent to note that demonstrations can be made in various ways and the approach to these formulas is scarcely mentioned in the books. The organization of school knowledge allows us to introduce a new pedagogical practice of the teacher, in which the process of reflection and interpretation about different procedures allows us to establish a relation between theory and everyday life. With the proposals here reported it is desired to continue adding new elements capable of enriching and making more accessible the process of construction of mathematical knowledge in this area. Since all mathematical theoretical knowledge that has existed before by actual experience, our preoccupation with contextualizing isoperimetric inequalities in their initial event, as well as punctuating some questions of the development of mathematics, proving how much it has arisen, is and will be relevant to the development of man.
