Bugs item #956730, was opened at 20040519 10:04 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=956730&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: integrate(x^n,x,0,inf) => sinrx error Initial Comment: integrate(x^n,x,0,inf); Is n positive, negative, or zero? neg; Is n + 1 positive, negative, or zero? neg; Is n an integer? y; Error: $x is not of type LIST. Error signalled by SINRX. The integral is of course divergent, but it should not be getting an internal error. Why does it even ask whether n is integral? Strangely, with n noninteger, it correctly diverges.  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=956730&group_id=4933
