The actions of the difference operator (http://planetmath.org/FiniteDifference) D and the tangent operator (http://planetmath.org/TangentMap) d on the 16 propositional forms in two variables are shown in the Tables below.

Table A7 expands the resulting differential formsMathworldPlanetmath over a logical basis:

{(dx)(dy),dx(dy),(dx)dy,dxdy}.

This set consists of the singular propositionsPlanetmathPlanetmathPlanetmath in the first order differential variables, indicating mutually exclusive and exhaustive cells of the tangent universe of discourse. Accordingly, this set of differential propositions may also be referred to as the cell-basis, point-basis, or singular differential basis. In this setting it is frequently convenient to use the following abbreviations:

x=dx(dy) and y=(dx)dy.

Table A8 expands the resulting differential forms over an algebraic basis:

{1,dx,dy,dxdy}.

This set consists of the positive propositions in the first order differential variables, indicating overlapping positive regions of the tangent universe of discourse. Accordingly, this set of differential propositions may also be referred to as the positive differential basis.
