On coconvex approximation In Lp [-1,1} ,1 ≤ p ≤ ∞

الملخص EN

Let a function , ƒ€ Lp (I)1, which changes convexity finitely many times at Ys by piecewise polynomial and dividing difference for the interpolating polynomial which are coconvex with it.

In this paper we discuss the estimate of the degree of approximation of ƒ by using the divided difference and weighted D.
