The fractional derivative D^qf(s) (0@?s@?1) of a given function f(s) with a positive non-integer q is defined in terms of an indefinite integral. We propose a uniform approximation scheme to D^qf(s) for algebraically singular functions f(s)=s^@ag(s) (@a-1) with smooth functions g(s). The present method consists of interpolating g(s) at sample points t"j in [0,1] by a finite sum of the Chebyshev polynomials. We demonstrate that for the non-negative integer m such that m=q-m-1. Some numerical examples in the simplest case 1
