Strogatz's Dogs

Steven Strogatz proposed a pursuit problem with N dogs starting at the vertices of a regular N-gon. Dan Anderson made a beautiful processing investigation: http://openprocessing.org/sketch/226722 And Mike Lawler had a good Family Math discussion over it: https://mikesmathpage.wordpress.com/2015/10/31/talking-about-steven-strogatzs-n-dogs-question-with-kids/ Then Simon Gregg in Scratch: https://scratch.mit.edu/projects/86082416/#player #somanytools Once upon a time I tried to model a pursuit problem in GeoGebra, but couldn't. I thought I should try again. This only has four dogs, but you can arrange them as you want and vary their speeds.
