Answer:

The lower the Delta E, the closer the colors are to each other. A delta E of zero indicates that there is zero difference between the two colors. The higher the Delta E, the further apart the colors are and more color difference is preceived.

The relationship between the operators E and D is \displaystyle \sf{E  \equiv \:   {e}^{hD}     }

Given :

The operators E and D

To find :

The relationship between the operators E and D

Solution :

Step 1 of 2 :

Define shift operator E

For any arbitrary function f(x) the shifting operator or shift operator E is defined as

\displaystyle \sf{ Ef(x) = f(x + h) }

Where h is the Step length

Step 2 of 2 :

Find relationship between E and D

Using Taylor's Theorem we get

\displaystyle \sf f(x + h) = f(x) + hf'(x) +  \frac{ {h}^{2} }{2!} f''(x) + \frac{ {h}^{3} }{3!} f'''(x) + . \: . \: .

\displaystyle \sf \implies Ef(x ) = f(x) + hDf(x) +  \frac{ {h}^{2} }{2!} {D}^{2}  f(x) + \frac{ {h}^{3} }{3!}  {D}^{3} f(x) + . \: . \: .

\displaystyle \sf \implies Ef(x ) = \bigg[1 + hD+  \frac{ {h}^{2} {D}^{2} }{2!}   + \frac{ {h}^{3} {D}^{3} }{3!}  + . \: . \: .\bigg] f(x)

\displaystyle \sf \implies Ef(x ) =  {e}^{hD}  f(x)

\displaystyle \sf \implies E  \equiv \:   {e}^{hD}
