Teorema de Herão: uma aplicação da identidade de Euler.

Abstract

In this work we carried out a bibliographic study on the mathematician Leonhard Euler. We deduce the Euler constant through an application of Financial Mathematics. We present some concepts of Real, Complex and Plane Geometry Analysis, such as: Complex numbers, Numerical Sequences, Infinite Series in particular (Taylor and Maclaurin), congruence of triangles. We show Euler's Identity and finally We state and prove Heron's Theorem.
