I'm not sure how I was supposed to guess that from the question "How can I write a polynomial f(x^2-4,x^2-2*x) in sage?" Have you read all that the reference manual has to say on multivariable polynomial rings (see http://www.sagemath.org/doc/reference/polynomial_rings/polynomial_rings_multivar.html)? That would seem to be relevant. > On Thu, Apr 4, 2013 at 4:36 PM, John Cremona <[email protected]>wrote: > >> Like this? >> >> sage: R.<x,y> = QQ[] >> sage: f = x^2+y^2 # for example >> sage: f(x^2-4,x^2-2*x) >> 2*x^4 - 4*x^3 - 4*x^2 + 16 >> >> John Cremona >> >> On 4 April 2013 12:58, Neda <[email protected]> wrote: >> > >> > Hello >> > How can I write a polynomial f(x^2-4,x^2-2*x) in sage? >> > thank you >> > >> > -- >> > You received this message because you are subscribed to the Google >> Groups >> > "sage-support" group. >> > To unsubscribe from this group and stop receiving emails from it, send >> an >> > email to [email protected]. >> > To post to this group, send email to [email protected]. >> > Visit this group at http://groups.google.com/group/sage-support?hl=en. >> > For more options, visit https://groups.google.com/groups/opt_out. >> > >> > >> >> -- >> You received this message because you are subscribed to the Google Groups >> "sage-support" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected]. >> To post to this group, send email to [email protected]. >> Visit this group at http://groups.google.com/group/sage-support?hl=en. >> For more options, visit https://groups.google.com/groups/opt_out. >> >> >> > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/sage-support?hl=en. > For more options, visit https://groups.google.com/groups/opt_out. > > > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
