See here, on pages 2 and 3. Does that answer your question?
Hi
I would find the soultion for this but I just know there definitons
For any constant nonzero positive real numberp, find the delta exponential function ep(t; 0)
and the nabla exponential function ˆep(t; 0) for T := hZ. Show that one can be written in terms
of other (i.e. write a relation between them).
I would appreciate any help
