The unit circle is a circle with a radius of 1, centered at the origin of a coordinate plane. It plays a central role in trigonometry because every point on the unit circle corresponds to an angle and its sine and cosine values. If you take an angle measured from the positive x-axis, the coordinates of the point where the terminal side of that angle intersects the circle are exactly (cos θ, sin θ). This makes the unit circle a powerful tool for understanding the behavior of trigonometric functions and for visualizing relationships between angles, coordinates, and periodic patterns. It also forms the foundation for defining sine and cosine beyond right triangles, allowing their extension to all real numbers.
