Chapter 11: Lists 167
• Edit any element of a list to which a formula is attached.
• Use the stat list editor (Chapter 12).
• Use
ClrList or ClrAllList to detach a formula from a list (Chapter 18).
Using Lists in Expressions
You can use lists in an expression in any of three ways. When you press Í, any expression is
evaluated for each list element, and a list is displayed.
•Use
L1–L6 or any user-created list name in an expression.
• Enter the list elements directly.
• Use y K to recall the contents of the list into an expression at the cursor location
(Chapter 1).
Note: You must paste user-created list names to the Rcl prompt by selecting them from the
LIST NAMES menu. You cannot enter them directly using Ù.
Using Lists with Math Functions
You can use a list to input several values for some math functions. See Appendix A specify for
information about where a list is valid. The function is evaluated for each list element, and a list is
displayed.
• When you use a list with a function, the function must be valid for every element in the list. In
graphing, an invalid element, such as L
1 in ‡({1,0,L1}), is ignored.
• When you use two lists with a two-argument function, the dimension of each list must be the
same. The function is evaluated for corresponding elements.
This returns an error.
This graphs
X…‡(1) and X…‡(0), but skips
X…‡(L1).
