Editing the Equation
In the Numeric Solver, press C until the cursor is on the equation. The screen
automatically changes to show only the
eqn: line. Make your changes, and then press

Specifying an Initial Guess and/or Bounds (Optional)
To find a solution more quickly or to find a particular solution (if multiple solutions exist),
you can optionally:
• If you see the error shown to the right,
delete the entered variable value. Then
edit the equation to use a different
variable.
Note: This error occurs if you use a
reserved name incorrectly or refer to an
undefined system function as a simple
variable without parentheses.
• Enter an initial guess for the unknown
variable. The guess must be within the
specified bounds.
• Enter lower and upper bounds close to
the solution.
For example, y1(x) is
undefined and you
use y1.
Initial guess must be
within the bounds.
