Limit
Does anyone know how to prove x^n tends to 0 for fixed x in [0,1)? Somehow I can't recall how to do the simplest of things. Money is tight (talk) 15:10, 9 April 2011 (UTC)
 * $$x^n$$ is a decreasing sequence bounded below, so it has a limit. The limit L must be a fixed point of $$L\mapsto xL$$, so L=0. Sławomir Biały  (talk) 15:20, 9 April 2011 (UTC)
 * Thanks, that's a very clever proof. Money is tight (talk) 04:21, 10 April 2011 (UTC)
