Hi Jose, Many thanks for your response and help; I tried the Padé approximation routine, and this is 'better', but I'm still seeking the ubiquitous Chebyshev 'equioscillation' (or 'alternation') behaviour in terms of *absolute* error. Am I missing something simple here <doh!>? For what I am seeking (equioscillation), it appears that Mathematica only optimizes for *relative* error. Have I missed a more basic command that does what I want?
