A factored form of complex analytic functions and its application to finding partial fraction decompositions. (English) Zbl 0901.30019

The authors improve the algebraic method for partial fraction decomposition taught in calculus. They show that the coefficients are solutions of a linear system of equations with a triangular matrix which is easy to find.
