I really like your triangle center videos. Nicely chosen properties worth knowing and nice presentation with well-motivated demonstrations.

Thanks 😊

I'm feeling good after solving each of the minor problems that you outlined in the solution. Thanks to you!

[@littlefermat]

Glad to hear that!
The best progress is achieved when you pause, try, and only then continue watching 👍

Nice work 🤎

[@aashsyed1277]

what about the cauchy functional equation? they are ended?

[@littlefermat]

Of course not!
I am just alternating between the geometry and fe tutorials.
