GeoGebra e o método de Briot & Bouquet para a resolução gráfica de equações cúbicas

In the mid-nineteenth century, french mathematicians Briot and Bouquet have proposed an intriguing graphical method for solving cubic equations "depressed" - the third degree equations that do not have the quadratic term. The proposal is simple geometric construction, though based on an ingenious algebra. We propose here the verification and testing graphical method through an instructional sequence using the software GeoGebra also present the ingenious algebraic development that resulted in this graphic method for determination of real roots of a cubic equation of the type x³ + px + q = 0 where p and q are real numbers. The method states that these solutions are summarized in the abscissas of the points of intersection of the circumference containing the origin and the center C (-q/2, 1-p/2) with the parable y = x².

A questão da experiência estética nos debates de epistemologia da comunicação

In the outline of communication epistemology, the article discusses the fluid and complex delimitations of the field of social communication and its intersections with the world of aesthetics. It includes the question of aesthetic experience and its presence in the epistemological debates on communication in Brazil. It tries to identify possible contributions of the phenomenology of aesthetic experience, based upon the teachings of Mikel Dufrenne and the theoretical references proposed by John Dewey, Paul Valéry, Luigi Pareyson and Jacques Rancière, to the studies on communication. To contextualize the articulations between communication and aesthetics in the debates developed in the Working Group on Communication Epistemology, the article briefly explores the works that discussed that intersection over the last ten years.
