[sage-support] How to express fraction field elements as (lazy?) power series?

2009-08-16 Thread Simon King
Dear Sage supporters, assume that one has an element of the fraction field of a univariate polynomial ring, say sage: R.t = QQ[] sage: p = 1/(t^2-2*t+1) How can one express p as a formal power series? More precisely: How can one obtain the coefficient of, say, t^100 in said power series?

The answer really depends on if your server is on an intranet LAN (inaccessible from the rest of the world) or on a (public) internet web server. In the former case, the answer is very easy and even I can answer your question! On Sun, Aug 16, 2009 at 9:49 AM, John Cremonajohn.crem...@gmail.com

Actually, I probably spoke out of turn. The :8000 at the end of the url specifies the port to use, so https shouldn't be using the default port. But, there could be a firewall preventing port 8000 from working, or a port forwarding problem if your server is hiding behind a router. I
