Outside of schools, anyone use the @geogebra graphing calculator much? If so, what do you use it for?

I have used it many times, mostly to gain intuition into some math. For instance, in my SVD post https://waynemystir.github.io/blog/2018/01/10/svd-1 …, I describe the best least squares fit using a few graphs that I created with
@geogebra . Graphing arbitrary objects in R2 or R3 is really easy and quick.
Thanks, this is great. BTW, you may enjoy my very simple proof of the SVD here: http://cognitivemedium.com/emm/emm.html (Not the main point of the article.)

Actually your awesome proof of SVD was part of the inspiration for me to write that post. The video included in your proof was very helpful for building intuition!!
