• Paste a Y= variable name from the VARS Y-VARS menu to the equation solver.
• Press
y K, paste a Y= variable name from the
VARS Y-VARS menu, and
press
Í. The expression is pasted to the equation solver.
The expression is stored to the variable eqn as you enter it.
3. Press
Í or †. The interactive solver editor is displayed.
• The equation stored in eqn is set equal to zero and displayed on the top line.
