This function plots the roots of the characteristic equation on the complex plain and super imposes the Unit Circle to show if a root is inside, outside or on the Unit Circle. The modulus and absolule reciprical are also displayed.
unit.circle.wge(real = 0, imaginary = 0)returns a plot of the root with respect to the unit circle
