Proposta de abordagem para as técnicas de integração usando o software Geogebra

Abstract

This paper proposes an approach for the integration techniques - which serves as a supplement for those who are worked by the authors of differential calculus books and Integral (CDI). Its overall objective is to structure and propose teaching situations supported in Digital Technology, more precisely in the Geogebra software on the integration techniques, where the graphic-geometric patterns related to integrandas and their primitive functions are explored. The organization's research followed the two initial stages of Didactic Engineering (ED) - Preliminary Analysis and Analysis the Priori. The structuring of educational sessions involving different situations-problems, respected the stages of Fedathi Sequence - Taking position, maturation, Solution and Proof. We started working with the lifting of the issue - identify the content, integration techniques, is in the textbooks of CDI discipline, cited in Teaching Unit Program (PUD) Course Degree in Mathematics from IFCE - Juazeiro, worked only through algebraic character. With the intention of we record this observation, we made comments on ways to approach the authors Stewart (2010), Guidorizzi (2011) and Leithold (1994), where we could go on record that, in fact, there is a limitation on holding patterns graphic-geometric relating to Techniques: Variable Substitution, For Parties, Partial Fraction and Replacement Trigonometric. As an educational product, it developed a "site" where we provide the video classes and their teaching sessions.
