Here are some examples of the unit circle:
- When θ = 0°, the coordinates are (1, 0), so cos(0°) = 1 and sin(0°) = 01.
- When θ = 45°, the coordinates are (√2/2, √2/2), so cos(45°) = √2/2 and sin(45°) = √2/22.
- When θ = 30°, the coordinates are (√3/2, 1/2), so cos(30°) = √3/2 and sin(30°) = 1/23.
These examples illustrate how the unit circle can be used to find the sine and cosine values for various angles.
