Complex numbers in results, including list elements, are
displayed in either rectangular or polar form, as specified
by the mode setting or by a display conversion instruction
(page 2

i
and
Radian modes
are set.
Rectangular-complex mode recognizes and displays a
complex number in the form
a+b
i
, where
a
is the real
component,
b
is the imaginary component, and
i
is a constant
equal to
-1
.
To enter a complex number in rectangular form, enter the
value of
a
(
real component
), press
Ã
or
¹
, enter the value
of
b
(
imaginary component
), and press
y
[
i
] (constant).

Polar-complex mode recognizes and displays a complex
number in the form
re^

, where
r
is the magnitude,
e
is the
base of the natural log,
q
is the angle, and
i
is a constant equal
to
-1
.
To enter a complex number in polar form, enter the value
of
