Hey! I’ve created an animated tutorial explaining slope trick using manim - 3blue1brown’s animation library. You may have read ZSCoder/Kuroni’s blogs on slope trick and as far as I know, those are the only tutorials on the topic, and there aren’t any videos explaining it. Visualisations really do help for a topic like slope trick where you might have to sketch several different curves before thoroughly understanding it. I hope you find this helpful! Feel free to provide any feedback/video recommendations! Don’t forget to like/comment/subscribe!
