On the Zeros of the Polar Derivative of a Polynomial %K Coefficients %K Polynomial %K Polar Derivative %R %X Let P(z) be a polynomial of degree n whose coefficients satisfy an ≥ an−1 ≥ ... ≥ a0 > 0.Then according to the Enstrom-Kakeya Theorem, all the zeros of P(z) lie in |z|≤ 1. 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. %U https://www.cna-journal.com/article_90790_2852e2deafb164d3d3a16c46e2963ff7.pdf
