Syntax
------

TAN(N)

where N is a numeric variable in radians.

Examples
--------

::

   T = TAN(2.56)

sets T equal to the value of the tangent of 2.56 radians.

::

   PRINT TAN(2.56)

gives:

::

   -.65744712167262

Remarks
-------

The argument is expressed in radians.

The tangents on angles in degrees may be calculated as follows :-

::

   A = TAN(angle/180*PI)
