Factoring is an important process for the teaching of algebra, and this presentation shows the most common cases for different algebraic expressions.

Husserl left many unpublished drafts explaining (or trying to) his views on spatial representation and geometry, such as, particularly, those collected in the second part of Studien zur Arithmetik und Geometrie (Hua XXI), ...

The trigonometric functions of special angles are a relevant topic in the subject of Trigonometry because often addressed in the different content areas and their relation to the different branches. There is a link on the ...

This work aims to present an introduction to Afim and Projective Geometries and their main resources through groups of transformations. Thus, it defines its properties, presents the theorems and the results of each geometry. ...

This monograph explores the Taxicab Geometry that due to its peculiar way of measuring distances, which differs from Euclidean geometry that we used, some problems loci were explored, as well as applications such as the ...

This presentation shows and defines the different types from Models that the Investigation of Operations works.
