For an accurate uniform analog simulation, uniformly continuous functions should be expressed in a full range of the given domain by approximations of the form: f(x)ap;α_0+α_1x+α_2x^β_1+α_3x^β_2 It is noticeable that the exponentsβ_1, β_2 are respectively determined by real numbers according to the nature of the given function. A maximum error due to this approximation is given by a moderate value enough to be used for this purpose, and its magnitude is comparable with that caused by other approximations having an equal number of parameters. The usefulness of this approximations can be found in the fact that different values of the parameters are available for a wide range of approximation. A numerical method how to determine the parameters is with its computing program and an optimum approximation obtained by this procedure is shown with its error curve. As for different functions, numerical data are tabulated.
