Homework Statement
"The transformation T from the z-plane to the w-plane is given by
[itex]w=\frac{1}{Z-2}[/itex]
where [itex]Z=x+iy[/itex] and [itex]w=u+iv[/itex]
Show that under T the straight line with equation [itex]2x+y=5[/itex] is transformed to a circle in the w-plane with centre [itex]\left ( 1,-\frac{1}{2} \right )[/itex] and radius [itex]\frac{\sqrt{5}}{2}[/itex]
The Attempt at a Solution
I've worked out that the line [itex]2x+y=5[/itex] can be written in locus form as [itex]\left|Z-10\right|=\left|Z+10-10i\right|[/itex]
