This is a problem with the version of Maxima that we are shipping: Maxima 5.16.3 http://maxima.sourceforge.net Using Lisp CLISP 2.46 (2008-07-02) Distributed under the GNU Public License. See the file COPYING. Dedicated to the memory of William Schelter. The function bug_report() provides bug reporting information. (%i1) limit(2*9.81*(t^2-1)/(t-1),t,1); (%o1) 39 It seems to be fixed in the current version of Maxima: Maxima 5.17post http://maxima.sourceforge.net Using Lisp SBCL 1.0.18.debian Distributed under the GNU Public License. See the file COPYING. Dedicated to the memory of William Schelter. The function bug_report() provides bug reporting information. (%i1) limit(2*9.81*(t^2-1)/(t-1),t,1); (%o1) 39.2400016784668 We should really upgrade. --MIke --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
