Este artigo discute o uso do software GeoGebra em atividade de modelagem que integra conteúdos de geometria e funções reais de variável real, com possíveis desdobramentos para trabalhos de natureza interdisciplinar. É apresentada uma experiência realizada em curso de licenciatura, na qual os alunos mostram, no processo de modelagem de movimentos, o desenvolvimento de habilidades que são características do raciocínio matemático - estabelecer relações, fazer conjeturas, resolver problemas.
For fixed positive integers r and k, and a fixed kuniform hypergraph F , we look for n-vertex hypergraphs that admit the maximum number of r-edgecolorings with the property that there is no copy of F for which all hyperedges are assigned different colors. We consider) , the k-uniform expanded complete graph, and we prove that the Turán hypergraph, the balanced ℓ-partite k-uniform hypergraph on n vertices, is the only extremal configuration for any ≥ ℓ r r k ( , ) 0 and large n.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
