Don't memorize the unit circle! Do this instead!

Stop! Don't memorize the unit circle! There's a much simpler way to do trig problems, and in this video we show you exactly what it is! By learning the two "special triangles" (30-60-90 pi/6 - pi/3 - pi/2 and 45-45-90 pi/4 - pi/4 - pi/2) you can do trigonometry problems much more easily!
