Category: Lisp Core  Integration Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Raymond Toy (rtoy) Assigned to: Nobody/Anonymous (nobody) Summary: integrate(x/(1x^2),x) and integrate(x/(x^21),x) Initial Comment: integrate(x/(1x^2),x) and integrate(x/(x^21),x) don't ask if x < 1 or x > 1. Because of this we get two different results, when they should be equivalent, depending on the range of integration.  >Comment By: Dan Gildea (dgildea) Date: 20110124 16:25 Message: (%i2) integrate(x/(1x^2),x); (%o2) log(1x^2)/2 (%i3) integrate(x/(x^21),x); (%o3) log(x^21)/2 The two results are equivalent except for their sign, and a constant term of log(1). I don't understand the problem.  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1430843&group_id=4933
