Math, Angle, and Test Operations 2-17
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 2.19). In the example below, re^qi and Radian modes
are set.
Rectangular-complex mode recognizes and displays a
complex number in the form a+bi, 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 à 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^
q
i, 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 r (magnitude), press y [ex] (exponential function),
enter the value of
q
(angle), press y [i] (constant), and
then press ¤.
