Trig Ratios for Special Angles • [4.3d] PRE-CALCULUS 12

Pre-Calculus lecture video looking at how to use special triangles to determine trig ratios for special angles in standard position related to π/6, π/4, and π/3. Examples include both primary and reciprocal ratios.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.

Corresponds to chapter 4, section 4.3 in McGraw-Hill's Pre-Calculus 12, but also fits with the trigonometry unit from almost any other Pre-Calculus course or textbook.
