Changes http://wiki.axiom-developer.org/273FactorExpressionIntegerDoesNothing/diff -- While this is "mathematically sound", it can be very frustrating to new users of Axiom. Is this behavior explained in a FAQ somewhere? Maybe something should be added to section 8.2 of the 30-year book?
To get what the OP wanted, recast the problem as a Polynomial:<br> f:=(y-1)*sin(x)+y-1 -- original function<br> g:=subst(f, sin(x)=sx)::Polynomial Integer -- remove the nonlinear operators, then recast<br> h:=factor(g) -- yields (sx + 1)(y - 1)<br> <p> Unfortunately, any conversion of h from a "Factored Polynomial Integer" to a "Factored Expression Integer" will destroy the factorization. -- forwarded from http://wiki.axiom-developer.org/[EMAIL PROTECTED]
