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.
