In this project, solutions to second order linear recurrence equations with constant coeffi- cients have been investigated. We have used generating functions to derive the general solution to the homogeneous equation and we show that in general the particular solution is complicated to find. By limiting the right hand side (RHS) in the equation to a polynomial-exponential family of functions we c

I. Why ReignCom?
The reason that we selected ReignCom as our subject for analysis is because the company is an excellent example of how an organization can take steps in changing its structure to overcome poor progress.
Surely ReignCom had good times and its success story was a famous one in the industry. Things turned bad for the company within few years, with the advent of strong riva
