ARAÚJO, Marcos Vagner da Silva.
Resumen:
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.
