Graphical Theory
Here is a Visual Theory of the " Time Vector "
1) Set D is All of Space represented by variable " a "
2) Dimension (a) : Time Space Set : subset { a( 54) }
3) Subset ( a (54) ) Variables : { t, v, a, i, i^2, x, y }
4) The shaded parts are the actual parts of the Graph of " a " = ( 3 v + a )/2 : where v = velocity ; a = acceleration.
