Subject: help for trig functions (PR#199)
Message-ID: <199905261353.PAA00615@pubhealth.ku.dk>

The help for trig functions (e.g. ?tan) says 
Description:

        These functions give the obvious trigonometric func-
        tions.  They respectively compute the cosine, sine,
        tangent, arc-cosine, arc-sine, arc-tangent and arc-tan-
        gent of two arguments.

1. I think it would be useful to state that the arguments are in radians
(not degrees).

2. only atan2 expects two arguments, the rest take one argument.
