[sage-support] Limits and recurrence relations

2008-02-02 Thread Hector Villafuerte
Hi, is there a way in SAGE to handle recurrences? Say, determine the closed-form expression, or the limit as n goes to infinity, of something like: r_0 = sqrt(a), where a>0 r_n = sqrt(a + r_{n-1}) Now, experimenting with SAGE (and using some basic Calculus), I've noticed that this recurrence co

Hello, Here is an example of the underlying problem sage: a = -x/(2*x-4) sage: e = lambda e: taylor(e,x,3,4) sage: e(a) -3/2 + x - 3 - (x - 3)^2 + (x - 3)^3 - (x - 3)^4 sage: type(_) sage: b = e(a)._maxima_(); b x-(x-3)^4+(x-3)^3-(x-3)^2-9/2 What happens is that is able to construct a Symbolic

Here we go with Sage 2.10.1.rc5. This is the *final* rc and it will be identical with the final 2.10.1 release modulo any critical bug fixes that will pop up over the next 12 hours. The release is planned for the tonight (PST). We finally fixed the ATLAS build issue that would cause very long bui
