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 a degree,
gradian or radian angle, according to the current
angle mode. You can use
ó ,
G
o r ô to override
the angle mode setting temporarily.

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:
