Select(

xListName

yListName

)

Selects one or more specific data points from a scatter plot or
xyLine plot (only), then stores the selected data points to
xListName

and yListName (Chapter 14)

SetLEdit

ãcolumn1ListName

column2ListName

...

column20ListName

Sets up the list editor;

SetLEdit

with one to 20 ListNames loads

them in the specified order;

SetLEdit

with no arguments removes

all current list names from the list editor and enters the default
lists

xStat

yStat

, and

fStat

to columns 1, 2, and 3

Form("

formula

listName

)

Attaches formula to listName; formula resolves to a list, which is
dynamically stored and updated in listName (page 162)

Using Mathematical Functions with Lists

You can use a list as a single argument for many TI

-86 functions; the result is a list. The

function must be valid for every element in the list; however, when graphing, undefined
points do not result in an error.

When you use lists for two or more arguments in the same function, all lists must have the same
number of elements (equal dimension). Here are some examples of a list as a single argument.

{1,2,3}+10

returns

{11 12 13}

‡

{4,16,36,64}

returns

{2 4 6 8}

{5,10,15}

{2,4,6}

returns

{10 40 90}

sin {7,5}

returns

{.656986598719

.958924274663}

3+{1,7,(2,1)}

returns

{(4,0) (10,0) (5,1)}

{1,15,36}<19

returns

{1 1 0}

Selecting SetLE from the
menu pastes SetLEdit to the
cursor location.

You can create new list
names as SetLEdit
arguments.
