comment Mathematica 9 behavior with derivative of a sum
@swish No matter what you expect it to mean, you will have to agree that if D[Sum[Sin[x],x],x] has a nonzero value, then D[Sum[f[x],x],x] cannot be zero in general, since we might have f==Sin.

comment Function with different set of arguments
@user4972 Because of the way Sequence works, p cannot be used directly as a list, you have to use for instance {p}[[i]].

comment Function with different set of arguments
@user4972 Yes, the first two examples where to highlight how you would go about if you knew exactly what numbers it should work for.

comment Function with different set of arguments
@user4972 In the above you know for certain that definition 1 has one passed, and definition 2 has three passed. In the last definition, the matched p be equal to Sequence[{x,y,z},{x1,y1,z1},...,{xN,yN,zN}], so you can find the length using Length[{p}]. Note that {} is needed due to the way Sequence works.

comment Edges and crossing
Look at reference.wolfram.com/mathematica/ref/Line.html . The syntax is Graphics[{Line[{{0,0},{1,1}}]] to draw a lince between points {0,0} and {1,1}. You can use styling to make the latest line appear visually on top. But initially you'll get better help if you try to just make a simple example code demonstrating what you would like to do.

comment Changing the number of locators with SetterBar
In case you don't know, there is a LocatorAutoCreate option for LocatorPane that adds/removes points when alt-clicking.

comment Quirk in VertexColors interpolation when displaying Polygon
It would be nice to see some code pieces, you can always just reference your other answer with respect to interfacing triangle.
