Lesson 17: Solving for a Variable—Numerically
If you want a mimeric solution for an unknown in an equation, you
can use the root-finding application (HP Solve). You can solve for a
value of any variable without changing the ecjuation—as long as you
fill in values for all other variables in the expression or ecfuation.
You can solve an equation or expression over and over—for different
known values, and for different combinations of known and unknown
variables.
Exaiiiple:
Solve the following expression for x:
6 4 2
+
.(■- -“9 ' 6 + r — x~ ' x~ + 5r + 6
This expression was created by the TEACH command
earlier and stored as the variable, RATFUNC in the
EQNS directory.
Step 1: Begin the SOLV'E application and choose Solve
Equ-at i or........ „.

ENTER FUNCTION TD_ SOLVE
Step 2: The EQ= field is highlighted already, so choose RATFUNC
to be the current eciuation. You will need to swdtch to the
EQNS directory first.
