Abstract :In this work, the Faber polynomial expansions and a different method were employed to estimate the coefficients of a subclass of bi-close-to-convex functions, which is introduced by subordination concept in the open unit disk. Further, we generalize some of the previous outcomes.Keywords : Bi-univalent functions, Bi-close-to-convex functions, Coefficient estimates, Faber polynomial, Subordination
