Talk:Mean value theorem (divided differences)

[Untitled]

Note: Relevant discussion can be found at Talk:Divided differences. -Elmer Clark 05:11, 28 November 2006 (UTC) Here I give a mean value theorem of divided difference in terms of dd only that is without using derivative which is published in Mathematica Bohamica 2009. Theorem: If

[f,x0,x1, ... ,xn]<0<[f,y0,y1, ... ,yn] 

then there is z_i in [min{x_k,y_k,max{x_k,y_k] for i=1,2,...,n such that

[f,z₀,z₁, ... ,z_n]=0
