Wow, that was definitely not the direction I was anticipating this to take...
Robert's contribution is very interesting, though I'm not sure how indefinite integrals (without "+C") fit into that framework. As to the issue on the tracs, my view is that an indefinite integral is not a function in the same sense as a derivative, and that (unlike plot and diff) there are two really fundamentally different objects both referred to by the name "integral" (darn you, Leibniz!), so consistency is not as useful a guide for this. As far as I can tell, having integrate(sin(x), (x, 0, pi)) is no problem to add, nor multiple integration in general. The only problem (and presumably deprecation necessity) would be whether integrate (f,x,y,z) is a triple indefinite integral or a definite integral with y and z as endpoints. I've made my views known on this above :) As a side note, it is unfortunate that Python won't (will it?) allow integrate(f,(x),(y),(z)) to indicate the triple integral and needs the tuple notation integrate(f,(x,),(y,),(z,)). Of course it is easy to allow integrate(f,[x],[y],[z]) for this, but that certainly doesn't address the consistency question. - kcrisman --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
