TI-83 Plus Lists 298
Using Lists with Math Functions
You can use a list to input several values for some math functions. Other
chapters and Appendix A specify whether 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,
L
1})
, is ignored.
This returns an error.
This graphs
X
ä
‡
(1)
and
X
ä
‡
(0)
,
but skips
X
ä
‡
(
L
1)
.
•
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.
•
When you use a list and a value with a two-argument function, the
value is used with each element in the list.
