The Unit Circle is typically a tool students learn to use when they begin memorizing certain trigonometric ratios and special right triangles. Sometimes teachers will give a mnemonic device for when sine or some other function is positive, when they're negative, etc. It can also be helpful for remembering certain equivalencies between radian and degree measures of an angle. But the unit circle is too meaningful to use only as a simple memory tool. This Desmos implementation is intended to highlight certain relationships on the circle, so that students can more meaningfully discern what's happening and why.
