Hey, may I suggest calling it Trig Party? (trig.party is available as of this comment.)

Pretty nice.

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

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 the unit circle diagram like this, then it all made much more sense.

Interesting, I have always visualized tangent differently. A line perpendicular to the X axis that stops at the intersection with the extension of the radius line.

This is awesome! It might also make sense to draw out the sine or cosine curves as the point moves about the circle.

I think its same thing just in another point of view, here i rotate the canvas to explain my thought: https://image.ibb.co/ce0rye/qwe.png
