Abstract. The concept of polar composite polynomials was introduced by Zaheer and Alam [1] and was studied in quite a detail in the same paper. Some further applications were obtained by the authors in their subsequent articles [2], [3]. In the present paper the author applies the results of [1] to find the real values of certain partial fraction sums.
