Funções convexas e o problema de Steiner para Três Pontos

Abstract

This paper aims to present applications of mathematical theories (definitions, theorems and properties) as a tool to enrich teaching-learning in the school environment. As a suggestion we have here the presentation and development of the theory about convex functions and their main results (convex optimization). We seek to emphasize topics such as the body of complexes, where we present the polar form through Euler’s formula; topics of linear algeba and real analysis; convex sets and a brief history of their study; convex functions with emphasis on the sub-differential idea, as the main requirement for the optimization study. As an application of this theory, we solved Steiner’s problem for three points of the plane, which is mainly used in communication technologies among others.
