Analysis of the chaos dynamics in(Xn,Xn+1)plane
  in the last decade, studies of chaotic system are more often used for classical choatic system than for quantum chaotic system, there are many ways of observing the chaotic system such us analyzing the frequency with Fourier transform or analyzing initial condition distance with Liapunov Exponent, this paper explains dynamic chaotic process by observing trajectory of dynamic system in (Xn,Xn+1)
