Equation Displays the currently defined
equation.
Equation Variables Displays all equation variables and
their values.
bound
Default={M1©99,1©99}
Displays the
bound
limits that apply to
the unknown variable value for which
you are solving.
Solve
You select one variable, the one you
want to solve for, from this list.
Equation
The first line of the Equation Variables screen displays the
equation you defined on the
EQUATION SOLVER
screen.
If you would like to edit a defined equation, press $ until the
EQUATION SOLVER
screen is displayed. Edit the equation with
:, /, or - m, as necessary. Then press b to
return to the Equation Variables screen.
Equation Variables
All variables included in the defined equation are displayed. If
those variables have never been assigned a value, they are set
equal to 0. If a variable has been defined previously (for
example, from the Home screen), that value appears.
If a value extends beyond the screen, press " to scroll to the
end of the number. This is especially important if a number is
in scientific notation and you need to see whether it has a
negative or positive exponent.
For an equation with more than one variable, you must define
all variables except the unknown variable for which you want
to solve.
