A Limit ProblemDate: 10/24/96 at 14:5:54 From: Dallas Oler Subject: A limit problem What is the limit of (x^2 -4) / (2x) as x approaches infinity? Thank you, Dallas Date: 10/24/96 at 15:48:56 From: Doctor Donald Subject: Re: A limit problem Write it as x^2(1-4/x^2) ------------- = (1/2) x( 1-4/x^2) 2x As x approaches inf, 4/x^2 approaches 0, so we get large numbers x times 1/2 times stuff which is about 1. The net result is larger and larger products - the answer is infinity. -Doctor Donald, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
