O princÃpio de Cavalieri e suas aplicaÃÃes para cÃlculo de volumes / The Cavalieri principle and its application to calculation of volumes

Nicomedes Albuquerque Pontes 26 April 2014 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O trabalho foi construÃdo no sentido de evidenciar o ensino inadequado do cÃlculo de volume no Ensino MÃdio onde, na maioria das vezes, sÃo colocadas fÃrmulas para que alunos decorem, com o intuito de resolverem questÃes inerentes, sem nenhuma compreensÃo dos conteÃdos ou como surgiram. Portanto, o objetivo desse trabalho à apresentar como axioma o PrincÃpio de Cavalieri, para com aplicaÃÃes do mesmo, gerar um encadeamento das ideias, e chegarmos Ãs fÃrmulas dos volumes dos sÃlidos geomÃtricos mais comuns no Ensino MÃdio: o prisma, o cilindro, a pirÃmide, o cone e a esfera, destacando a forma mais clara de ensino desse conteÃdo para os alunos. / The work was constructed in order to reveal the inadequate teaching of the volume calculation in high school where, in most cases, formulas are placed so that students memorize in order to resolve issues involved, without any understanding of the content or how they came about. Therefore, the aim of this paper is to present as an axiom the principle of Cavalieri, towards the same applications, generate a chain of ideas, and get to the formulas of the volumes of common geometric solids in high school: prism, cylinder, pyramid, cone and sphere, highlighting the clearest form of teaching that content to students.

O PrincÃpio de Cavalieri como mÃtodo de demonstraÃÃo e fundamentaÃÃo para o cÃlculo de Ãreas e volumes / The Cavalieri's principle as a method of demonstration and justification for the calculation of areas and volumes

Wecsley Fernandes Lima 09 July 2015 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / It has been the Principle of Cavalieri , an effective axiom for demonstration areas calculation formulas and volumes , one math course content present throughout the Basic Education Brazil and always also found in external evaluations . The goal here is to show that the Cavalieri principle is very efficient and simple in the statement formulas areas of plane figures and volumes of solids , as this axiom simplifies the calculation of areas to measure segments and volumes in areas . Exposes the importance of such content in the basic training of students so that , we need to remedy the difficulties that they have , for about 30% of the race of Mathematics issues of external evidence is about geometry. Finally , we conclude that one should recognize the importance of this study for the construction of knowledge of the student and not try a ready-made thing , because only then it is more concrete learning. / Tem-se no PrincÃpio de Cavalieri, um axioma eficiente para demonstraÃÃo de fÃrmulas de cÃlculo de Ãreas e volumes, um conteÃdo da disciplina de MatemÃtica presente em todo o Ensino BÃsico do Brasil e sempre encontrado tambÃm nas avaliaÃÃes externas. O objetivo aqui à mostrar que o PrincÃpio de Cavalieri à muito eficiente e simples na demonstraÃÃo de fÃrmulas de Ãreas de figuras planas e volumes de sÃlidos, pois este axioma simplifica o cÃlculo de Ãreas ao medir segmentos e o de volumes em Ãreas. ExpÃe-se a importÃncia destes conteÃdos na formaÃÃo bÃsica dos alunos de maneira que, precisa-se sanar as dificuldades que eles tenham, pois cerca de 30% das questÃes de MatemÃtica das provas externas à sobre geometria. Por fim, conclui-se que se deve reconhecer a importÃncia desse estudo para construÃÃo do conhecimento do aluno e nÃo tentar uma coisa jà pronta, pois sà assim ele terà um aprendizado mais concreto.
