Três formas naturais de encontrar o número de Euler

Abstract

The Euler's number (e), unlike other irrational numbers such as Pi (π), is not associated with geometry, but rather with rates of change and growth of certain phenomena. In this context, the present study aims at exposing three ways of finding the Euler number (e) naturally, for this purpose, the study used qualitative exploratory research, more specifically a bibliographical research. These forms occur either by continually compounding compound interest, or by slicing a square of area equal to 1 into infinite smaller rectangles and distributing them under the hyperbola curve y = 1/x in the interval from x = 1 to x = x0, and even in games using regular polyhedra and playing cards.
