Projective Geometry gives us the means to demonstrate and discover properties of figures, it is a possibility to understand mathematically the study of the descriptive properties of geometric figures. And after Poncelet ...

In this work, concepts, definitions and theorems about Fuzzy Logic and Systems Based on Fuzzy Rules were presented. We used these systems to develop a mathematical model for diagnosing autism based on the CARS-BR scale: ...

The importance of teaching Geometry is a present theme in several researches in Mathematic Education (LORENZATO 1995, FONSECA et. al 2002; BRESSAN; BOGISIC; CREGO, 2010). These authors consider fundamental the presence of ...

The work developed with the use of playful materials plays a fundamental role in the teaching and learning of Mathematics, especially in the field of Spatial Geometry, carried out with high school classes. The didactic ...

This paper wants to provide subsidies to the Mathematics teacher of Basic Education, regarding to Determinants. From a consistent theoretical basis, it builds the concept of Determinant and deducts its main properties. ...

In this work we explain an elegant and accessible proof of the Fundamental Theorem of Algebra using the Lagrange Multipliers method. We believe this will be a valuable resource not only to Mathematics students, but also ...

In the routine of the pre-university courses one tends to work, in a year, the diverse contents which are studied in high school, often giving greater depth or emphasis on some subjects. There are already well-qualified ...
