In this research paper using the Chebyshev expansion, we explicitly determine the best uniform polynomial approximation out of P qn (the space of polynomials of degree at most qn) to a class of rational functions of the form 1/(T q (a) ยฑ T q (x)) on [-1, 1], where T q (x) is the first kind of Chebys
