The Form of Solutions and Periodic Nature for Some System of Difference Equations

Abstract

In this paper we study the form of the solution of the following systems of difference equations of order two xn+1 = (x_{n}*y{n−1})/(x_{n}+y_{n-1}) , yn+1 =( y_{n}*x_{n-1})/(\pm y_{n} \pm x_{n-1}) with nonzero real numbers initial conditions.
