Category: Share Libraries Group: None Status: Open Resolution: None Priority: 4 Private: No Submitted By: Barton Willis (willisbl) Assigned to: Nobody/Anonymous (nobody) Summary: absint (defined in fourie) Initial Comment: (%i1) load(fourie)$ (%i2) absint(abs(x^2-1),x,-1,1); (%o2) 0 The correct result is 4/3. The user documentation suggests that absint can integrate abs(sin(x)). But it gets this wrong too: (%i4) absint(abs(sin(x)),x,0,2*%pi); (%o4) 0 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=3160731&group_id=4933 |
