HELP SIN                                        Revised by Fran Evelyn, July 85

    sin(<angle>) -> number

SIN returns the sine of an angle. If the argument and result are 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.
