Thanks again,but why $f(x)=1$ for all x ?

Ben ,first of all thanks for the answer. I'd like to know why for example in the calculation of $E(1)$ we get $f(0)=1,f(1)=1,f'(0)=0$ . Thanks in advance

Thanks for the great answer, but I've got a question : why did you stop the Taylor series computation at the fourth derivative ? Why not at the third/fifth/sixth etc ?Moreover, why the order of approximation is the highest? Thank you once again.

@LutzL , I guess the appriximation will be a linear combination of the values

@LutzL , first of all thanks for the answer. The main problem I'm facing is proving the appriximation is of highest order, and I'd like to know how your suggestion helps proving it.
