HELP COS                                        Revised by Fran Evelyn, July 85

    cos(<angle>) -> <result>

COS returns the cosine of an angle. If the argument is to be in radians rather
than degrees, the variable POPRADIANS must be set to TRUE (see HELP
*POPRADIANS).

See REF *NUMBERS for details of numbers and mathematical operations available
in POP-11.
