AP Precalculus Unit 3.2 | How to Use the Unit Circle to Find Sine, Cosine & Tangent

In this AP Precalculus lesson, we introduce the unit circle and learn how to find sine, cosine, and tangent from a point on the circle. This video covers angles in standard position, radians, arc length, coterminal angles, and how trig ratios come directly from coordinates on the unit circle. This is Topic 3.2 – Sine, Cosine, and Tangent from the AP Precalculus curriculum and is part of my full AP Precalc trig series.
