<abstract>In this paper, the authors have introduced and investigated two subclasses, Halpha,beta(0<alpha<=1) Hgamma(0<alpha<=1) of Analytic and Biunivalent functions in the open unit disc . For functions belonging to these classes, the authors have obtained estimates on the first two Taylor-Maclaurin coefficients a2 and a3. The results of this paper will generalize some of the earlier known results.</abstract>
