S ClassPad Operation

 

(1) On the application menu, tap 

&.

• This starts up the System application.

 

(2) Tap [System] and then [Imaginary Unit] to display the 

Imaginary Unit dialog box.

 

(3) On the Imaginary Unit dialog box, select the type of 

imaginary unit you want to use.

In mathematics, the imaginary unit i allows the real number system R to be extended to the 
complex number system C.
In electrical engineering and related fields, the imaginary unit is often written as j to avoid 
confusion with a changing current, traditionally denoted by i.
Your ClassPad lets you specify either “ i ” or “ j ” for the imaginary unit. 

 

(4) After the setting is the way you want, tap [Set] to apply it and close the Imaginary Unit 

dialog box, or tap [Cancel] to close without changing the setting.
