Additive Two Card C00166

RBF DEFINITIONS
Additive Two:

"Column 7 accounts the extraction of the polar vertexes.
All systems have axes of spin. The axes have two poles.
Synergetics extracts two vertexes from all Euler topological
formulas to function as the poles of the spin axis.
Synergetics speaks of these two polar vertexes as the
additive two. It also permits polar coupling with other
rotative systems. Therefore a motion system can have
associability."
