tan()
μ key
tan(Va lu e1 ) ⇒ value
tan(List1) ⇒ list
tan(Val ue 1) returns the tangent of the argument.
tan(List1) returns a list of the tangents of all elements in List1.
Note: The argument is interpreted as a degree, gradian or radian
angle, according to the current angle mode. You can use ¡,
G
or R to
override the angle mode setting temporarily.
In Degree angle mode:
In Gradian angle mode:
In Radian 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:
tan
/
()
μ key
tan/(Va lu e1 ) ⇒ value
tan/(List1) ⇒ list
tan/(Va lu e 1) returns the angle whose tangent is Va l ue 1 .
tan/(List1) returns a list of the inverse tangents of each element of
List1.
Note: The result is returned as a degree, gradian or radian angle,
according to the current angle mode setting.
Note: You can insert this function from the keyboard by typing
arctan(...).
