Using A Different Expression - HP -28S Manual

Evaluate the expression.

To return to the previous problem, you would execute EE (to switch to
the EE directory), execute SPI (to switch to the SPI directory), and
press
I
SOLV

SOLVR
(to activate the Solver menu); all the variable val-
ues would be the same as when you left SPl.
Using a Different Expression
Now that you have two sets of values to use with the expression EQl,
try creating a second expression EQ2 that you can use with either set
of values. There are two basic steps:
1. Switch to the EE directory, create the new expression, and store
the new expression in a variable EQ2.
2. Switch to the SPI or SP2 directory, change the value of EQ from
'EQl' to 'EQ2', and use the Solver to evaluate the expression.
Step 1: Switch to the EE directory, create the new expression,
store the new expression in a variable EQ2.
and
Switch to the EE directory.

Create the new expression. In this example, EQ2 will be an edited
copy of the expression EQl.
