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:

tanê (
expression1
) returns the angle whose
tangent is
expression1
as an expression.
tanê (
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.
In Degree angle mode:
tanê (1) ¸ 45
In Gradian angle mode:
tanê (1) ¸ 50
In Radian angle mode:
tanê ({0,.2,.5}) ¸
