Math functions are all fixed now.  The problem was caused by 
inheriting math.h's definition of PI2 (which is pi/2) instead of
using trig.h's own definition of PI2 (which is 2*pi).  trig.h has
been changed to use its own definition now, a change which
affects only sincos.c and tan.c, since trig.h is a libroot private
header.

Good luck Stephan. :-)
