Algumas considerações sobre os números complexos

Abstract

In this research we will know a little more about the history of the complex numbers as Insufficiencies within the real numbers that motivated its emergence. In the course of the dissertation we will know where everything began, the emergence of the imaginary unity, and that same unity as a Path for the solution of third-degree polynomial equations. We will show how the Operations within this numerical set, its geometric and trigonometric form, we will also see some applications in other areas of human knowledge, such as the relation between the complex numbers and the electricity, which emphasizes the importance of this numerical set. Finally, we will make a survey of the pedagogical approach of the complex numbers in some of the books Used in school.
