MISCELLANEOUS:  NEW RESULTS

 There is only one cardinal way of learning mathematics - DOING MATHEMATICS - Halmos 
Mathematics from the foundations through its courses of developments, using rules of logic, abstractions and reason aided by the imagination of the thinking friend of the human mind, indeed is  more than any one of a common ordinary human languages. 
It is in fact a supra-language of the  greater universe in which the human language oscillates as a barrier and element of imperfection in   understanding the universe and  communicating with it.                                                                                                                                                                                                                                                                                                                                                                                                 ~  Dr. Dejenie Alemayehu Lakew  

  This module is for few results on a new kind of differential operator 
  which I obtained by exponentiang the  usual derivative : D = d/dx 
  with the natural  base : e^{D} 
  For the sake of simplicity in usage later, I will denote it by D^{∞} 

  Definition. e^{D}:=∑_{j=0}^{∞}((D^{(j)})/(j!)) 

  I put results in blocks as sub-modules of this module of results.
