Geometria diferencial das curvas planas /

Domingues, João Paulo Felipe. January 2013 (has links)
Orientador: Thiago de Melo / Banca: Vanderlei Marcos do Nascimento / Banca: Nivaldo de Góes Grulha Junior / Resumo: A história da Geometria Diferencial começa com o estudo de curvas. Noções de retas tangentes à curvas podem ser encontradas em Euclides, Arquimedes e Apolônio. Também, o Cálculo está baseado em ideias geométricas e, portanto, é natural encontrar investigações sobre curvas entre os tópicos tratados pelos pioneiros da Análise, Newton, Leibniz e Euler. Neste trabalho, serão apresentados os conceitos que fundamentam a teoria de curvas, bem como exemplos envolvendo algumas curvas clássicas, como a cicloide / Abstract: The history of Differential Geometry begins with the study of curves. Notions of tangent lines to the curves can be found in Euclid, Archimedes and Apollonius. Also, the Calculus is based on geometrical ideas and therefore is natural to find researches on curves between topics treated by the pioneers of Analysis, Newton, Leibniz and Euler. In this work, the concepts that underlie the theory of curves and some examples involving classical curves are presented, as the cycloid / Mestre
