DESCRIPTION

32       Basic trig functions. The input image is mapped through either  cos(3),
33       sin(3) or tan(3) and written to out. All work in degrees.
34
35       The  size  and number of bands are unchanged, the output type is float,
36       unless the input is double, in which case the output is  double.   Non-
37       complex images only!
