The Boundary Propertieses of Some Functionals in Class Cβα

This paper presents a certain method to determine the range of variability ( or the set of values) of some functionals defined in the Class (i.e the class of analytic functions in the unit disk It have been shown in this class that the range of variability of the functional is the closed diskThe estimations of modulus of function and some other estimations related were also obtaind.
