HP 48gII I\@@OK@@, 0.25\`~‚a`, 3V5³~a12`K, R:„Ô3#2#1™³K, z1: ³3+5*„¥³~„z1K, Q:³~„r/„Ü ~„m+~„r™™³~q`K

•RPN mode

(Use I\@@OK@@ to change to 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⋅105 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™³K

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~„z1K
