Topic: Some animated graphs for teaching basic Trigonometry

Just a few graphs I have used with my students. I prefer a black background for reducing glare.

animated pedal sine, animated pedal cosine
calc > animate
The pedal turns round and the graph is swept out

three figure bearings
(does anyone know how to get the green number to show 005 or 029 instead of 5 or 29?)

Re: Some animated graphs for teaching basic Trigonometry

That's smart. I wouldn't guess that a function may be used as a point's coordinate. Thank you for sharing this!
