Figure 7

This figure shows the behavior of the solutions of ${\mathit{x}}_{\mathit{n}\mathbf{+}\mathbf{1}}\mathbf{=}\frac{{\mathit{x}}_{\mathit{n}}{\mathit{y}}_{\mathit{n}\mathbf{-}\mathbf{2}}}{{\mathit{y}}_{\mathit{n}\mathbf{-}\mathbf{1}}\mathbf{(}\mathbf{-}\mathbf{1}\mathbf{+}{\mathit{x}}_{\mathit{n}}{\mathit{y}}_{\mathit{n}\mathbf{-}\mathbf{2}}\mathbf{)}}$ , ${\mathit{y}}_{\mathit{n}\mathbf{+}\mathbf{1}}\mathbf{=}\frac{{\mathit{y}}_{\mathit{n}}{\mathit{x}}_{\mathit{n}\mathbf{-}\mathbf{2}}}{{\mathit{x}}_{\mathit{n}\mathbf{-}\mathbf{1}}\mathbf{(}\mathbf{-}\mathbf{1}\mathbf{-}{\mathit{y}}_{\mathit{n}}{\mathit{x}}_{\mathit{n}\mathbf{-}\mathbf{2}}\mathbf{)}}$ , since we consider the initial conditions equals ${\mathit{x}}_{\mathbf{-}\mathbf{2}}\mathbf{=}\mathbf{0.32}$ , ${\mathit{x}}_{\mathbf{-}\mathbf{1}}\mathbf{=}\mathbf{0.25}$ , ${\mathit{x}}_{\mathbf{0}}\mathbf{=}\mathbf{-}\mathbf{0.31}$ , ${\mathit{y}}_{\mathbf{-}\mathbf{2}}\mathbf{=}\mathbf{0.23}$ , ${\mathit{y}}_{\mathbf{-}\mathbf{1}}\mathbf{=}\mathbf{0.26}$ and ${\mathit{y}}_{\mathbf{0}}\mathbf{=}\mathbf{0.17}$ .
