Detaching Formulas from List Names Detaching a Formula from a List Name You can detach (clear) a formula from a list name in any of four ways. • In the stat list editor, move the cursor onto the name of the list to which a formula is attached. Press Í ' Í. All list elements remain, but the formula is detached and the lock symbol disappears. • In the stat list editor, move the cursor onto an element of the list to which a formula is attached. Press Í, edit the element, and then press Í. The element changes, the formula is detached, and the lock symbol disappears. All other list elements remain. • Use ClrList (page 12.20). All elements of one or more specified lists are cleared, each formula is detached, and each lock symbol disappears. All list names remain. • Use ClrAllLists (Chapter 18). All elements of all lists in memory are cleared, all formulas are detached from all list names, and all lock symbols disappear. All list names remain. Editing an Element of a FormulaGenerated 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-83 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. 12-16 Statistics
