sage: K.<d,e,p,g,m,f,u,v,j,N> = FractionField(PolynomialRing(QQ,10,'depgmfuvjN')) sage: R.<s> = K[] sage: w=u sage: u=0 sage: w u
Why doesn't Sage answer 0 for the value of w here? More generally, if I have some complicated expression and I assign a value to one of its variables, Sage knows the value I've just assigned, but it doesn't propagate into the value of previously defined expressions using that variable. Please comment and please tell me how to force the substitution to take effect in previously defined expressions. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
