Hence the horizontal plane contains the Re(x) ([equivalent to] G) and Im(x) ([equivalent to] H) axes, thus forming the Argand plane, whilst the vertical plane given by GA or GB represents the Cartesian plane for each surface.
2] + x - 5, given by x = 1, -2 [+ or -] i, described at the end of the section entitled Cubic polynomials in the Cartesian plane.
Figure 8(a) shows another instance where the complex conjugate roots are not evident in the Cartesian plane.
n] - 1 in the Cartesian plane and the resulting n-roots which invariably appear in the Argand plane.
A simple plot of this equation in the Cartesian plane is shown in Figure 2.
It is understood that the GA and GB planes represent the Cartesian plane for each surface.
This confirms the GA (or GB) plane is in fact the Cartesian plane.
For instance, by extending the solution space of Equation (2) to now include complex numbers, it is evident that the original x-y plot in the Cartesian plane is merely a two-dimensional 'slice' of a much more general three-dimensional surface.
The beauty of this method is that it always places the roots in the complex Argand plane, which is orthogonal to the Cartesian plane in which the quadratic equation was originally presented.
