    My New Mathematical Identities (Verify them) on a new kind of 
     differential operator I defined by:  ∑_{k=0}^{∞}((D^{(k)}/(k!)

    1.  ∑_{k=0}^{∞}((D^{(k)}(cos x))/(k!)) = cos(x+1)
    2.  sin x+∑_{k=1}^{∞}((D^{(k)}(sin x))/(k!)) = sin(x+1)
    3.  ∑_{k=0}^{∞}((D^{(k)}(e^ (x))/(k!)) = e^(x+1)

                                          - Dejenie Alemayehu Lakew
  
    More new results and conjectures on the new operator
   that I defined on the left are posted on my 
   ResearchGate site in Math group under the category:

  Communications in Mathematics Teaching:CMT

  Check it out ! I welcome comments or counter
  examples on the conjectures.

 "A mathematician, like a painter or poet, is a maker of patterns. If his patterns are  more permanent than theirs, it is because they are made with ideas"

"Mathematics has to be studied not only because it is useful, but because
 it is also beautiful, as it is a study of structures of logic and reason that   transcends the expanse of imagination"
