[Bug 166120] Goal Seek does not work for certain root expression
https://bugs.documentfoundation.org/show_bug.cgi?id=166120 --- Comment #7 from Markus Mohrhard --- You can't solve this with a real valued solver for negative x. The function f(x)=x^(1/x) is complex valued in the domain x < 0 and there are only a few real valued solutions in that domain. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=166120 --- Comment #6 from Mike Kaganski --- (In reply to unok from comment #5) Maybe (when I looked for the name for functions that are not continuously defined, in my language, it returned the word that I translated like that - maybe poorly). However, you were given the explanation of what I meant, in comment 1. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=166120 --- Comment #4 from Mike Kaganski --- (In reply to unok from comment #3) No idea what kind of "excuse" that fact could be (it is a cryptic phrase, that looks as having no sense to me); but my point was - it is not reasonable to expect solvers to find solutions of irregular functions. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=166120 --- Comment #1 from Mike Kaganski --- IMO, this is not a bug. The function x^(1/x) is not contiguously defined for x < 0. That there are some points where it's defined is possible to know by human. But I may be wrong, I don't know much about numerical algorithms. -- You are receiving this mail because: You are the assignee for the bug.
