Solver Function
This function enables you to find any variable in an equation.
Entering and solving an equation
The solver function is used as follows.
1. Press b 0 to enter the NORMAL mode.
2. Enter both sides of an equation, using ‘=’ and variable names.
3. Press I 5.
4. Enter the value of the known variables.
5. Move the cursor (display) to the unknown variables.
6. Press @ h.
• The solver function can find any variable
anywhere in an equation. It can even find
variables that appear several times in an
equation.
•You can use both global and local
variables in your equation. (See page 58.)
• Using the solver function will cause variables memory to be overwritten
with new values.
•To exit the solver function, press j.
Changing the value of variables and editing an equation
When you are in the solution display, press e to return to the display for
entering values of variables, then return to the equation display in the
NORMAL mode by pressing j.
