k Absolute Value and Argument
Calculation
Supposing the imaginary number expressed by the
rectangular form
z = a + bi is represented as a point in the
Gaussian plane, you can determine the absolute value (
r)
and argument (
␪ ) of the complex number. The polar form
is r⬔ ␪ .
• Example 1: To determine the absolute value (
r) and
argument (
␪ ) of 3+4i (Angle unit: Deg)
(r = 5 , ␪ = 53.13010235 °)
(r  5 ) A A R 3 + 4 i T =
( ␪  53.13010235 °) A a R 3 + 4 i T =
• The complex number can also be input using the polar
form
r⬔ ␪ .
• Example 2:
2 ⬔ 45  1  i
(Angle unit: Deg)
L 2 A Q 45 =

Display
You can use the operation described below to convert a
rectangular form complex number to its polar form, and a
polar form complex number to its rectangular form. Press
A r to toggle the display between the absolute value
(
r) and argument ( ␪ ).
