Nice proof, very satisfying! I enjoyed that you used just the definition of an ellipse, the triangle inequality, and isometry of reflection. Since these are defining properties of the geometric objects I imagine that this proof is quite general
I loved watching this -- very elegant proof!!
This made me rethink ellipses- very cool!
Great explanation! I had to re-watch some parts because geometry isn't my strong suit, but it was still easy to follow and fun to think about
Nice! I'll remember this trick when I next teach conics.
Very nice!
Okay I can finally understand this! Thanks a lot! Great video!
very cool :0
