You will see six of the seven variables listed at the bottom of the

screen: p1, z1, R, Q, A12, α.

• RPN mode

Use the following keystrokes to store the value of –0.25 into variable

α: 0.25\` ~‚a`. At this point, the

screen will look as follows:

This expression means that the value –0.25 is ready to be stored into

α. Press K to create the variable. The variable is now shown in

the soft menu key labels:

To enter the value 3×10

into A12, we can use a shorter version of

the procedure: 3V5³~a12` K

Here is a way to enter the contents of Q:

Q: ³~„r/„Ü

~„m+~„r™™ ³~q` K

To enter the value of R, we can use an even shorter version of the

procedure:

R: „Ô3#2#1™ ³~r `K

Notice that to separate the elements of a vector in RPN mode we can

use the space key (#), rather than the comma (‚í ) used

above in Algebraic mode.

z1: ³3+5*„¥ ³~„z1 K(if

needed, accept change to Complex mode)

p1: ‚å‚é~„r³„ì*

~„rQ2™™™ ³ ~„p1™` K.

The screen, at this point, will look as follows:

You will see six of the seven variables listed at the bottom of the

screen: p1, z1, R, Q, A12, α.
