Complex Numbers
... We can look at the field from last example as another approach to complex numbers. We identify complex numbers with points of the Cartesian plane (or vectors anchored at the origin) and we call this “geometrical interpretation of complex numbers”. A point z of the plane can be identified by its Cart ...
