The key to understanding trigonometric functions is understanding the unit circle. However, to a beginning student of trigonometry, this can seem like a difficult task. In this video, I show how the unit circle can be simplified using a few key memory aids. It turns out, there are only 5 reference angles to memorize and their trigonometric values are related.
