Hello everybody !!!
I just met what I believe is a Sage bug if not a misuse of it from my
behalf, and I have no idea of how to create the corresponding ticket,
symbolics not being my field in any way. besides, I produced this bug
using the sage version with is installed in sage.math ( recompiling
the new version at the moment, I do not have any Sage available ). It
may be solved already but here it is anyway :
sage: var('delta k')
sage: m1=2*delta**2 + 2**2*delta*k
sage: n=delta*k+2
sage: m2=(2*delta)**2+(k-1)*4
sage: m=(delta+delta*k-(delta-1))
sage: ((m1/n)-(m2/n)).expand().simplify()
I will find another way to compute this, I was just too lazy to use
paper, so I am not blocked in any way, but this remains a bug that may
be created by a more clever use of Sage :-)
Thankkkkks !!! :-)
Nathann
