Ceva's theorem - Wikipedia

Yes, it's a fun one to prove but only applicable to a situation where a triangle has 3 concurrent cevians! Ceva's theorem - Wikipedia share.google/i3XFwvJKKEeS...

I used same-height triangles to label areas of the triangles in terms of x, and then I applied Ceva’s theorem:

I found out that if you have four adjacent Fibonacci numbers e,f,g,h then eh and 2fg are two elements of a Pythagorean triple.
1,1,2,3 - 3 and 4
1,2,3,5 - 5 and 12
2,3,5,8 - 16 and 30

I am teaching calculus for the 3rd year, and would also love to access your warmup questions if you are willing to share!

So, you think you're bad at math... YouTube video by Courtney Gibbons

Back on Twitter, my most viewed tweet was a link to my "math pep talk"—a video I made for my students that now has 23K views 👀

There's a lot to expand on in that video, like structural barriers to success in math. But I'm sharing it again anyway.

I turned my most boring math lesson into one of my most engaging ones. Here's how:

Great wonder and exploration here! There's so much fun to have with quadratics; here are just a few nonroutine problems I put into Desmos folders 📂:
