Using the STO command
A simpler way to create a variable is by using the STO command (i.e., the
K
key). We provide examples in both the Algebraic and RPN modes, by creating
the remaining of the variables suggested above, namely:
•
Algebraic mode
Use the following keystrokes to store the value of –0.25 into variable
α
:
0.25\ K ~‚a
. AT this point, the screen will
look as follows:
This expression means that the value –0.25 is being stored into
α
(the
symbol suggests the operation). Press
`
to create the variable.
The variable is now shown in the soft menu key labels when you press
J
:
The following are the keystrokes required to enter the remaining
variables:

~„m+~„r™™ K~q`
R:
