z1: 3+5*„¥ K~„z1` (if needed,
accept change to Complex mode)
p1: ‚е‚й~„r³„ì*
~„rQ2™™™ K~„p1`
.
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 .
• RPN mode
Use the following keystrokes to store the value of –0.25 into variable
α:
.25\`³~‚a` . At this point, the screen
will look as follows:
With –0.25 on the level 2 of the stack and ' α' on the level 1 of the
stack, you can use the K key to create the variable. The variable is
now shown in the soft menu key labels when you press J:
To enter the value 3 ×10 5
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: ~„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.
