ProfessorElvisZap posted on YouTube some educational videos:

completing the square #1, and #2,
Drawing the hypercube #1 and #2
Proving the chain rule
solving inequalities involving absolute values.

All are first or second takes done in real time and on chalk boards.

He plans to record his famous calculus rap and post it soon. I very much look forward.



  1. I recommend
    First watch:
    and then watch:
    Calc rap.

    Yes there is a typo on the first board, fixed toward the end of the video, and yes I did state the chain rule incorrectly while writing it, but corrected it on the next chorus.

    I don’t like doing multiple takes because the material becomes stale to the performer.
