Let Q(x) be polynomial of degree q interpolating x m at the points x-i, i = 0, 1, ..., q, where xi are zeros of the Tchebysheff polynomial of degree q + 1 on the interval [0, 1]. If q is of order x/m, then Q(x) approximates x m well enough. This result is used to obtain a good approximation to the s
