Abstract

The concern of present article is to study approximation properties of generalized form of Post-Widder operators. The modified operators conserve polynomial function αs(v) = v s , s ∈ N. we find some error in estimation of these operators with help of different approximation tools like usual, weighted and exponential modulus of continuity. The rate of convergence of these operators is also shown by numerical table and graphically using mathematica.

Keywords

Post-Widder operators, Peetre’s K-functional , Exponential modulus of continuity, weighted modulus of continuity.
