Viewing the Roots of Polynomial Functions in Complex Variable: The Use of Geogebra and the CAS Maple
Alves, Francisco Regis Vieira
Acta Didactica Napocensia, v6 n4 p45-58 Dec 2013
Admittedly, the Fundamental Theorem of Calculus-TFA holds an important role in the Complex Analysis-CA, as well as in other mathematical branches. In this article, we bring a discussion about the TFA, the Rouché's theorem and the winding number with the intention to analyze the roots of a polynomial equation. We propose also a description for a method that involves a complementary perspective for the use of two mathematical softwares. Thus, with the intention of checking the TFA and other mathematical properties related with the polynomial equation roots, we enphazise the visualization, an exploration with the Geogebra and the computer algebric system-CAS Maple. This CAS permits execute complex algebric operations and the visualization of tridimensional objects. On the other hand, the software Geogebra makes possible the dynamic mathematical exploration of the sciencific concepts in the teaching context of CA.
