Abstract :Many researchers have recently acquainted and researched several interesting subfamilies of bi-univalent function family ???? and they have found non-sharp estimates on the first two Tay-lor-Maclaurin coefficients |????2| and |????3|. In this current work, the subfamily of bi-univalent functions in the sense of symmetric conjugate points with quasi subordination is defined. The Maclaurin coefficients |????2|, |????3| and besides related with these coefficients |????3 − ????22| for functions belonging to this subfamily are derived. Further some corollaries are also presented.Keywords : Bi-Univalent Functions, Quasi- Subordinations, Symmetric Conjugate Points
