Abstract
Some rational approximations which share the properties of Padé and best uniform approximations are considered. The approximations are best in the Chebyshev sense, but the optimization is performed over subsets of the rational functions which have specified derivatives at one end point of the approximation interval. Explicit relationships between the Padé and uniform approximations are developed assuming the function being approximated satisfies easily verified constraints. The results are applied to the exponential function to determine the existence of best uniform A-acceptable approximations.
