7. The point P represents the complex number z in an Argand diagram. Point P moves on the curve C given by the equation

| z – 4 + 4i| = 2| z – 1 + i|

(a) Show that C is a circle whose equation may be written z k= , giving the exact value of k.

(5)

(b) Draw an Argand diagram showing the circle C and the points representing the complex numbers 1 – i and 4 – 4i.

(3)

(c) For the points on the circle C, find the maximum and minimum values of 4 4iz − + .

(3)

The transformation T from the z-plane to the w-plane is given by 8w zz

= + .

(d) Show that T maps the curve C onto a line segment in the w-plane and define this line segment by giving its equation and the coordinates of its end points.
