This surprised me today: > limit(1/x, x=0) Infinity
I was expecting something more like this: > limit(x/abs(x), x=0) und The help on Infinity wasn't illuminating: > Infinity? Type: PlusInfinity String form: +Infinity ...and so forth. This implies to me that Infinity and +Infinity are the same, but Sage seems to give a different result for the one-sided limit: > limit(1/x, x=0, dir='right') +Infinity Why am I getting a different answer this time? I'll grant that Sage eventually simplifies them to the same: > (limit(1/x, x=0, dir='right') == limit(1/x, x=0)).full_simplify() 1 > (limit(1/x, x=0, dir='left') == limit(1/x, x=0)).full_simplify() 0 ...but they print differently for some reason, and in any case I don't see why Sage would report a limit when the two one-sided limits disagree. The documentation on limit didn't help, either. Is this a bug, or do I misunderstand something? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
