Another stange thing. Was:
(%i1) c: %pi/3 - a - b$
(%i2) bc: sin(a)*sin(3*c)/sin(a+b);
(%o2) sin(a)*sin(3*b+3*a)/sin(b+a)
Now:
(%i1) c: %pi/3 - a - b$
(%i2) bc: sin(a)*sin(3*c)/sin(a+b);
(%o2) sin(a)*sin(3*(-b-a+%pi/3))/sin(b+a)
According to the user manual, Maxima was able to do
(%i1) declare(j, integer, e, even, o, odd)$
(%i2) sin(x + (e + 1/2)*%pi);
(%o2) cos(x)
(%i3) sin(x + (o + 1/2)*%pi);
(%o3) -cos(x)
But in the current CVS version:
(%i1) declare(j, integer, e, even, o, odd)$
(%i2) sin(x + (e + 1/2)*%pi);
(%o2) sin(x+%pi*(e+1/2))
(%i3) sin(x + (o + 1/2)*%pi);
(%o3) sin(x+%pi*(o+1/2))

The behavior was changed in order to avoid calling expand in the core simplifier
(trigi.lisp rev 1.31)

Could I remove these examples from the user manual?
