In this paper we obtain certain results for the polar derivative of a polynomial , , having all its zeros on , , which generalizes the results due to Dewan and Mir, Dewan and Hans. We also obtain certain new inequalities concerning the maximum modulus of a polynomial with restricted zeros. [Editor’s note: There are flaws in the paper, see M. A.
