message: There appears to be two definitions of locus floating about.  
One talks about the locus of a point:  It seems to imply that the locus of a point is the path taken by the point when it moves in some (usually constrained) manner.
The other (in this article) says that a locus is a set of points.   Specifically, that set of all possible points that satisfy the constraint.  
While the outcome may similar,  so these seem very different to me, at least in a strict mathematical sense.  To a novice first seeing this, the two models will seem quite different.  In the first we think of a point moving about, and it's locus is an attribute of that one point.  In the other we must start by explaining that the plane is composed of an infinity of points packed into a sheet.  The locus then somehow selects the candidate set of points that satisfy the criteria and chucks the rest. 
Which one?  I prefer the locus of a single point, but I wonder what others think?
:I think the two ideas are the same, though I don't know where you are seeing this "locus of a point" usage, so maybe you could point out instances of those.  The locus of a point is the set of points that make up the path determined by the movement of the point.  That is, the condition (or constraint) is that the points must be part of the path.  Since a path is a set of points, there is no reason for confusion. (p.s. remember to sign your comments with four tildes) Doctormatt 05:23, 31 October 2006 (UTC)

thread_title:  Stub? 

message: An IP user insists for removing "(disambiguation)" from the "other uses" field of the hatnote. This is against MOS:HATNOTE, where all examples of "other uses" display "(disambiguation)". This is also against the primary use of a hatnote, which is helping readers to find the article they want as easily as possible. If "(disambiguation)" is omitted, the reader has to think that, because of the plural of "other uses", the target article should be a disambiguation page. This reasoning may be difficult for a reader who is not accustomed with Wikipedia. Also, "(disambiguation)" appears explicitly after "other uses" in all whatnots that I have ever seen. Therefore having a specific style for this particular article may be confusing for some readers. Thus it is much better to be clear that the target is a dab page, and I will restore "(disambiguation)" again. D.Lazard (talk) 04:45, 2 January 2018 (UTC)
