Aziz and Mohammad have shown that under the same condition on coeffients the zeros of P(z) whose modulus is greater than or equal to n/(n+1) are simple. In this paper, we extend the above result to the polar derivative.}, keywords = {Coefficients,Polynomial,Polar Derivative}, url = {https://www.cna-journal.com/article_90790.html}, eprint = {https://www.cna-journal.com/article_90790_2852e2deafb164d3d3a16c46e2963ff7.pdf} }
