Absolute Value And Argument Calculation; Rectangular Form ↔ Polar Form Display - Casio fx-3650P User Manual

kAbsolute 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 (
number. The polar form is
• Example 1: To determine the absolute value (
i
3 + 4 (Angle unit: Deg)
r
( 5 )
( 53.13010235 °)
• The complex number can also be input using the polar form
• Example 2: 2
(Angle unit: Deg)

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
