On Approximation Properties of Stancu Type Post-Widder Operators Preserving Exponential Functions

In this article, Stancu type Post-Widder operators are introduced, which a modification of the that preserve functions constant and e^2ax for fixed a>0. The uniform convergence these modified function f on [0,∞) is examined then rate investigated with help continuity module. Voronovskaja asymptotic formula obtained to examine behavior operators. Finally, numerical examples graphs given show Post- Widder compared Post
