Table

var1
]
Builds a table of the specified expressions or
functions.
The expressions in the table can also be
graphed. Expressions entered using the
Table
or
Graph
commands are assigned increasing
function numbers starting with 1. The
expressions can be modified or individually
deleted using the edit functions available
when the table is displayed by pressing
† Header
. The currently selected functions in
the Y= Editor are temporarily ignored.
To clear the functions created by
Table
or
Graph
, execute the
ClrGraph
command or
display the Y= Editor.
If the
var
parameter is omitted, the current
graph-mode independent variable is
assumed. Some valid variations of this
instruction are:
Function graphing:
Table
expr
,
x
Parametric graphing:
Table
xExpr
,
yExpr
,
t
Polar graphing:
Table

,
q
Note: The
Table
command is not valid for
3D, sequence, or diff equations graphing. As
an alternative, you may want to use
BldData
.
In function graphing mode.

tan(
expression1
)
returns the tangent of the
argument as an expression.
tan(
list1
)
returns a list of the tangents of all
elements in
list1
.
Note: The argument is interpreted as either a
degree or radian angle, according to the
current angle mode. You can use
ó
or
ô
to
override the angle mode temporarily.
In Degree angle mode:

tan(
squareMatrix1
)
⇒
squareMatrix
Returns the matrix tangent of
squareMatrix1
.
This is
not
the same as calculating the
tangent of each element. For information
about the calculation method, refer to
cos()
.
squareMatrix1
must be diagonalizable. The
result always contains floating-point
numbers.
In Radian angle mode:
