For real α( α >1), we introduce subclasses M(α)and N(α)of analytic functions f( z)with f( 0) = 0a ndf � (0) = 1i nU. The object of the present paper is to consider the coefficient inequalities for functions f( z)to be in the classes M(α) and N(α). Further, the bounds of α for functions f( z)to be starlike in U are considered.
