Oh, much better than the previous version I saw! Showing the actual circle and not using sin function is the key, I think.

Thanks! I thought about it right after I uploaded the other version.

Agreed a good display of the relationship between a circle and a sine wave, Also very impressed that you did it without the sin function, it shows a deeper understanding.

Very interesting and well done. I think a short "about" to describe what we see would help students understand the significance of this model.
