Like I said, you should provide a concrete example for whoever actually tries to answer your question (probably not me). Something that a person can immediately use, e.g. a public sage worksheet or a link to a sagecell would help even more: http://sagecell.sagemath.org/ William > > > > On Sunday, May 10, 2015 at 10:57:43 AM UTC-5, William wrote: >> >> On Sun, May 10, 2015 at 8:43 AM, Phoenix <[email protected]> wrote: >> > I have a polynomial which is of degree ~500 and a number $k$. >> > I want to check two properties, >> >> Your question is far too ambiguous.
