Actually, sage: assume(x,'complex') sage: integrate(x*cos(x^3),(x,0,0.5)) integrate(x*cos(x^3), x, 0, 0.5) so the reason it works is because Maxima doesn't even evaluate it in the version of Maxima we have, so it goes straight to numerical integration with .n(). Anyway, upgrading our Maxima will take care of this integral. -- 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 URL: http://www.sagemath.org
