Aproximações de raízes de funções polinomiais através de métodos numéricos iterativos

Abstract

The present work addresses the numerical methods of Bissection, False Position and Newton to approximate zeros of polynomial functions of any degree, given the intervals in which these functions cancel each other, or when it can be deducted, or in scenarios where such intervals can be inferred. It is noteworthy that the research comprises the elaboration of algorithms and demands computational in order to solve problems, in accordance with the aspects provided for in the National Common Curricular Base. The use of the educational software Visual Numerical Calculation and Excel was decisive for the efficiency of the algorithms in terms of speed and accuracy.
