When computing the limit of a function I don't quite seem to be getting the behaviour that I expected.
--- sage: f(x) = 1 / x sage: print f.limit(x=0) sage: print f.limit(x=0, dir='minus') --- The first limit returns infinity, but I would expect it to return that the limit is not defined. The second (directional) limit confirms this (it returns -infinity). I was assuming that the default 'direction' for a limit is None and that a two directional limit would be computed (which in this case does not exist). Here's some of the help file that shows why I am perhaps confused: --- INPUT: - ``dir`` - (default: None); dir may have the value 'plus' (or '+' or 'right') for a limit from above, 'minus' (or '-' or 'left') for a limit from below, or may be omitted (implying a two-sided limit is to be computed). --- If anyone could clarify this I'd appreciate it.
