To be fair, integrals.wolfram.com has already done that for a while. > > Jason The following page is particularly relevant to Vinzent's remark: http://www.wolframalpha.com/examples/Math.html, e.g. the last example calculates various things about the 8_1 knot, including braid rep, Kaufmann polynomial etc. Or, PrimeOmega[1000] yields 6 and explicitly states it's computed by Mathematica. You can even do things like "solve 3x+4y=5 over the integers". The answer to "solve y^2=x^3+1 over the integers" was substantially less helpful, though technically correct, I think. But typing in Partitions[1000] yields that Wolfram Alpha isn't sure what to do with your input (perhaps Alpha doesn't have the Combinatorica package installed); even "Partitions" as input yields that result, which surprises me, because a dictionary-like entry shows up for "partitions". Probably that bug will get fixed soon, one would hope. So it is useful for casual computation and homework stuff, for sure - which is a good resource to have freely available, kudos to Wolfram for that. But it doesn't look like it is even close to free Mathematica notebook usage, either in having full capabilities (yet) or in being able to structure things, write programs etc. For what it's worth, - 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 -~----------~----~----~----~------~----~------~--~---
