i do not understand we began with one directrice and when he draws ellipse he talks about symmetry and another directrice, it must be half an ellipse the solution.
Why not find equations of a plane intersecting a cone. That provides everything but vector calculus is needed. Dandelin spheres come naturally with vectorial analysis.
The prof. Alan Goriely has written a very beautiful book 'Applied Mathematics: A very short introduction. Oxford University Press; 2017'.
Great lecture - loving the props ❤
Muito bom e interessante sobre equivalências de cônicas
why the video's recording quality is so much better than the recording on ox' material webpage?
Thanks prof. Alan 🌠
(3+7+31+127)×2 = (28×6)×2 This is the perfect geometric figure.

Simple y faci, genial!.... y con Wolfram Mathematica, mejor!

Your grammar is strangely foreign.
