Understanding Exact Trig Ratios: A Step-by-Step Guide
In today’s lesson, we're diving deeper into the topic of exact trigonometric ratios and how to derive them for specific angles. This article will explore examples to clarify how to calculate sine, cosine, and tangent of various angles, especially focusing on radians and using reference angles effectively.
Example 1: Finding Exact Trig Ratios for θ = 2π/3
In our first example, we need to find the trigonometric ratios for the angle θ, which is given as ( \frac{2\pi}{3} ).
