The
modulus
equation
says that
z
has fixed
distance
eight from
−
1
−
i
. Thus its locus is
a
circle
of
radius
eight centered at
(
−
1
,
−
1
)
, with Cartesian
equation
(
x
+
1
)
2
+
(
y
+
1
)
2
=
64
.
Figure 1.
The original
circle
,
a
horizontal stretch,
a
translation
and
a
quarter-turn
. Original
complex-plane
loci. The
map
u
=

x
+
i
y
stretches only the horizontal coordinate;
v
=
z

i
translates the
circle
;
w
=
i
v
rotates that translated
circle
about the origin. Marked dots show each center.
