      Absement is the total or cumulative displacement from an initial position, the antiderivative of displacement or distance. A multitude of derivatives/antiderivatives of displacement are now collected under the title "nth Derivatives" -- old idea, new words. A free Geometer’s SketchPad may be used to model this mathematics including time, definitions of derivatives, tangent lines, partitions, Riemann sums, absement and cumulative functions, and absement plus c. Function emojis, and GSP features of slide, and trace, will be shown in the context of absement.

      A passenger might wonder, "Does It Fit? Can the vessel get under the bridge?"
      In NJ/NY, there are traffic delays even on the waterways. Traveling at 5 knots, pushing a barge up the Hackensack is an all day trip made longer by "bridge openings," where river traffic and road traffic take turns on and above the river. Enjoy the ride aboard THE LIZ VINIK as Capt. Mike Vinik takes a barge northward.
