Oh sorry. Here is what I get:

MacOSx and my pocket calculator come to identical values, Solaris has a
different understanding of these functions. Any ideas?
I could work around the tan() problem by using sin(aa) / cos(aa)
instead instead of tan(aa). However, I don't know of a replacement for
atan() and I don't have my Bronstein handy right now. Any ideas?
Thanks!
Regards,
Andreas
