Helpful for understanding trig and the unit circle
From 3 comments
Very nice! I had a trig teacher years ago that taught only using formulas, without showing or explaining the unit circle. It was so confusing, hated the class until I discovered…
gedy on HNThis was very enlightening for me, thank you!
noneucat on HNWow...I never actually knew the significance of secant and cosecant, or how tangent/cotangents' lengths were related to the unit circle and right triangle. I knew the formulas to…

Nice, clear visualization
From 2 comments
This is a really nice visualisation. My only comment is that while canvas is certainly effective, if you built it in SVG you would only need to animate the points and not draw…
perilunar on HNThis is awesome! It might also make sense to draw out the sine or cosine curves as the point moves about the circle.

For some mental fun, try these values for the angle and see what observations you can make about the results: 76.34541 126.869896 137.50777 However, I find it a bit bothersome…

Drag glitch in fourth quadrant in Firefox

Pretty nice. It glitches on the 4th quadrant while dragging though, at least in Firefox.

Connect the diagram to graphs of the functions

This is awesome! Just a few days ago, as part of my schoolwork, I made this: https://www.geogebra.org/m/xcfev76v The color schemes we used are similar, I kind of copied mine from…
