Radiografía diferencial del teorema de MacLaurin-Cauchy para series numéricas

Abstract

[EN] In this article we give a new formulation and proof of the well-known integral criterion to study the carácter of a numerical series which terms are positives. This new approach is more intuitive because it allows to recognize, from a graphical point of view, the kind of functions that define the general term of convergent series as well as divergent ones.
