Summary: Weighted polynomial approximation of derivatives on the half line is considered. The weight $\textcent \sterling $########$${\S}$$###$\copyright \ddot $function will be of the form , a "folded" Freud weight. That is, that , where is a Freud !#"%$'\(\ddot 0)213"\%4\ddot $56798@ weight on . Linear processes which can be used for approximation of derivatives include interpolation, in "BAC$$####\{D}#####\{E}####$$F$\ddot $particular using node-sets recently developed by J. Szabados.
