- wodenokoto 11y agoThe animation shows 1 revolution for 1 rotation, but the text says its 2. That is very confusing.
- nitwit005 11y agoI was also confused by that until I changed my perspective. Watch the marker inside the circle. It starts pointing left. Half way around the inner coin it's pointing left again. At the end it's pointing left once more. That requires two rotations. The curve its graphing confuses things.
