How the Unit Circle Works
The unit circle is a circle with a radius of 1 centered at the origin of a coordinate plane. It's a powerful tool for understanding trigonometric functions, including sine, cosine, and tangent. The unit circle is divided into four quadrants, each representing a different set of coordinates (x, y). The angle θ (theta) is measured in radians, with π (pi) representing 180 degrees. As θ increases from 0 to 2π, the coordinates (x, y) change, allowing us to calculate the sine, cosine, and tangent values.
