Graphing calculator.

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:
5
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.
