Kabsolute Value And Argument Calculation; Krectangular Form ↔ Polar Form Display - Casio fx-100MS User Manual

k Absolute Value and Argument
Calculation
Supposing the imaginary number expressed by the
rectangular form
Gaussian plane, you can determine the absolute value (
and argument ( ) of the complex number. The polar form
r
is .
• Example 1: To determine the absolute value (
argument ( ) of 3+4
r
( 5 )
53.13010235 °)
(
• The complex number can also be input using the polar
r
form .
• Example 2:
k Rectangular Form ↔ Polar Form
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 ( ).
