Editing an Element of a Formula-Generated List Editing an Element of a Formula-Generated List Editing an Element of a Formula-Generated List Editing an Element of a Formula-Generated List
As described above, one way to detach a formula from a list name is to edit an element
of the list to which the formula is attached. The TI-84 Plus protects against inadvertently
detaching the formula from the list name by editing an element of the formula-generated
list.
Because of the protection feature, you must press
Í before you can edit an element
of a formula-generated list.
The protection feature does not allow you to delete an element of a list to which a
formula is attached. To delete an element of a list to which a formula is attached, you
must first detach the formula in any of the ways described above.
