How is the transformation of a point P in the z-plane to a point P' in the w-plane described in the chapter?

The transformation of a point P in the z-plane to a point P' in the w-plane is described by the equation w = f(z), where P' is the image of P. This transformation depends on the initial position of P and the specific transformation function used.

In complex analysis, the transformation from the z-plane to the w-plane is represented by the equation w = f(z). Here, z is expressed as z = x + jy, and w as w = u + jv, where the coordinates in the w-plane (u, v) are derived from those in the z-plane (x, y) based on the transformation function. Each point P in the z-plane corresponds to a unique point P' in the w-plane, which is referred to as the image of P. The transformation can be illustrated with examples, such as mapping specific points using defined functions.
