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.   "HHCC - Hand-Held Calculator Calculus" and Support Programs Qu.   What might a calc I teacher do to help students, who only have a TI-83, get easy access to its built-in calc functions as is easily managed on the TI-84? Ans. Program the TI-83.     This video: runs sample problem(s), provides programing instructions, provides the program and other calc I resources, guides the viewer through the programming.

 -- 'N' Stuff Portal Bridge Opening local     The LIZ VINIK with a light barge passes through the Portal Bridge, Hackensack, NJ on 10/7/2023.   State-of-emergency Snow Storm! - Nothing Closes NYC's 6th Boro State-of-emergency Snow Storm! - Nothing Closes NYC's 6th Boro - local     The States of NJ & NY were closed with "State-of-emergency conditions," but the vessels and crews of New York/New Jersey kept working. This is a 15-second clip of Capt. Mike's Vinik's view from THE VINIK NO. 6, during the storm of January 28th, 2022.   Does It Fit? Does It Fit? Bridges Over the Hackensack Does It Fit? Does It Fit? Bridges Over the Hackensack - local     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.
