Table CATALOG
Table expression1[, expression2] [, 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 expr, 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() TI-89: 2Y key TI-92 Plus: Y key
tan(expression1) ⇒ expression
tan(list1) ⇒ list
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 óor ôto
override the angle mode temporarily.
In Degree angle mode:
tan((p/4)ô) ¸1
tan(45) ¸1
tan({0,60,90}) ¸
{0 ‡3 undef}
In Radian angle mode:
tan(p/4) ¸1
tan(45¡) ¸1
tan({p,p/3,-p,p/4}) ¸
{0 ‡3 0 1}
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:
tan([1,5,3;4,2,1;6,ë2,1]) ¸
ë28.291… 26.088… 11.114…
12.117… ë7.835… ë5.481…
