Quadratic Test Run

I did this short video to try out my new document camera integrated with my Yeti microphone. I held the writing tablet in my lap at a convenient angle, used the adjustments of the camera to "flatten" and rotate the view to make it look right, and took the audio from my Yeti instead of the built-in mic in the camera. I used moderate lighting and all-in-all, I think it turned out pretty well.

The content of the video is a proof of the Quadratic formula,... pretty standard derivation which you might find helpful if it meets you "where you're at". Just keep in mind the real significance of this video is as a technical test run, not brilliant pedagogy. ... https://www.youtube.com/watch?v=RmwUjghPSt4
