Understanding The Unit Circle

Learn the unit circle the easy way. This complete unit circle tutorial covers everything you need for trigonometry, precalculus, and calculus: the key angles, the coordinates, radians and degrees, and how sine, cosine, and tangent all connect. If you have ever tried to memorize the unit circle and watched it fall apart on a test, this lesson is for you. Instead of brute force memorization, I show you where every value actually comes from, so it sticks for good. In this video you'll learn: What the unit circle is and why it matters in trigonometry The special angles (30, 45, and 60 degrees) and their radian equivalents How to find sine, cosine, and tangent from any point on the circle A simple way to memorize the unit circle without cramming How the unit circle sets you up for success in precalculus and calculus This is the same approach I use one on one with students at Alexander Tutoring, where we focus on the why behind the math so it sticks.
