In the present work, by considering a general subclass of univalent functions and using the Chebyshev polynomials, the author determine coefficient bounds for functions in this class.In particular, results, which are presented in this paper, are higher coefficient estimates on the coefficient |a 4 | and |a 5 | for functions in the function class.Furthermore, we provide the non-linear functional |a 2 a 4 -a 2 3 | for the class.2010
