The equation stored in
eqn is set equal to zero and
displayed on the top line.
•
Variables in the equation are listed in the order in
which they appear in the equation. Any values stored
to the listed variables also are displayed.
•
The default lower and upper bounds appear in the

Tip:
To use the solver to solve an equation such as
K=.5MV

When you enter or edit a value for a variable in the
interactive solver editor, the new value is stored in
memory to that variable.
You can enter an expression for a variable value. It is
evaluated when you move to the next variable.
Expressions must resolve to real numbers at each step
during the iteration.
You can store equations to any
VARS Y
.
VARS
variables,
such as
Y
1
or r
6
, and then reference the variables in the
equation. The interactive solver editor displays all
variables of all
Y=
functions referenced in the equation.
