Wow...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 calculate them, but not really what they truly meant. (Also, my username is relevant)

#22This 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 this image on Wikipedia: https://en.wikipedia.org/wiki/Trigonometric_functions#/media... I wonder if the author of this site did the same? What would be REALLY cool would be a connection between this diagram and the graphs of the functions:…
Actually i totaly go random with colors but its nice coincidence :) I really like it!
And about graphs of functions; yes! arriu suggested the same below, and this graphic from wikipedia is a good reference point for me, thanks! I have an idea to how to visualize graph of functions from unit circle to make it simple to understand! Will start to work on it in next week i hope.
Thanks for great suggestion, and if you make your work public i really would want to see it!

However, I find it a bit bothersome that the input field doesn't properly accept floats, and the floats get rounded unnecessarily. Please don't do that, or have an option to customize it.
Also, you miss the more obscure trigonometry values:

Namely, to quote from the above page:
Versine, Vercosine, Coversine, Covercosine, Exsecant, Excosecant, Haversince, Havercosine, Hacoversine, Hacovercosine
You might also wish to expand this by adding, in addition to the already shown degrees & radians, the following angle measures:
* Gradian * Turns * Arcminutes/Arcseconds

#25For 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 that the input field doesn't properly accept floats, and the floats get rounded unnecessarily.

Well the last one is. The significance of the other two angles, in OPs diagram, is unclear to me.

You're right, it was set as private but it's fixed now :)

And thanks about other great suggestions, those are really interesting. I'll check and try to bring them into party!

#29This was very enlightening for me, thank you!

#30My 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 the whole thing each time step. Admittedly not a big saving though.
