I don't always derive the reflective properties of ellipses but when I do they usually have amazing real world applications! View video notes on the Hive blockchain: peakd.com/mathematics/@mes/video-notes-conic-sections-ellipses-example-3-amazing-reflective-property
You could have stopped at 19:40. Your formula doesn't depend on x1 so that it applies to the mirror image construction swapping x for -x -- in otherwords for the other (positive) focus. Tan (alpha) has to be the same for the other line to (x1, y1).

Thank you for the video! Saved my life. Do you have one on hyperbola?
Glad to save your life! Working on the hyperbola one. But you can watch my older video on it though: ua-cam.com/video/Y6iYC4VEAi0/v-deo.html
Can you make this lesson in latex format for me please?
What textbook do you use?
Thanks for asking. I follow along this textbook: Calculus: Early Transcendentals Sixth Edition by James Stewart
@@mes thanks for sharing the book
thank you
Tq ❤️
