GeoGebra allows the manipulation of objects in the plane, in space and the representation of real or two-dimensional vector functions of two real variables. The creation of the Stereographic Projection tool of a point of the plane in the Riemann sphere, extended with the properties of the dynamic colours allowing the representation of coloured domains, allowed the development of applications that can be used, among others, in the teaching and learning of complex analysis topics. In this paper we present the essential tools and some of their applications in the teaching process.
O GeoGebra permite a manipulação de objetos no plano, no espaço e a representação de funções vetoriais reais uni ou bidimensionais de duas variáveis reais. A criação da ferramenta Projeção Estereográfica de um ponto do plano na esfera de Riemman, estendido com as propriedades das cores dinâmicas que permitiram representar os domínios coloridos, possibilitou o desenvolvimento de aplicações que podem ser usadas no ensino e da aprendizagem de tópicos de análise complexas entre outros. Neste artigo apresentamos o essencial da ferramenta e algumas das suas aplicações para o ensino.
