These are my approximation equations:
perimeter ≈ π[53a/3 + 717b/35 - √(269a^2 + 667ab + 371b^2)]
perimeter ≈ π(6a/5 + 3b/4)
If you can do better, submit it to Matt Parker's Maths Puzzles.https://www.youtube.com/watch?v=qJSHd...https://www.think-maths.co.uk/ellipse...
This was my pervious video featuring ellipsoids:https://youtu.be/l51LcwHOW7s
You can buy the ellipse from this video on eBay. I've written on my two new equations and signed it. All money goes to charity (the fantastic Water Aid).https://www.ebay.co.uk/itm/363096345270

Huge thanks to all who sent in a recording of them singing "A total ellipse of the chart." Sorry I could not include everyone. These are the people in the video:
It all started because of a request I put out on twitter.https://twitter.com/standupmaths/stat...
- So far the only times (I've noticed that) I say "eclipse" instead of "ellipse" are 5:01
which was just after talking about my wife who is a solar physicist. So I think we split the blame 50/50.
- It seems everyone but me recognised the Root Mean Square. I think I only associate that with current for some reason! Thanks all.
- Let me know if you spot any other mistakes!
Thanks to my Patreons who meant I could spend about a week trying to find approximations for the length of ellipses. "Are you still working on that?" Lucie would - rightfully - ask over the weekend. "I'm going the extra mile for my patreon people!" I would reply. Here is a random subset of those fine folks:
As always: thanks to Jane Street who support my channel. They're amazing.https://www.janestreet.com/
