The unit circle has a radius of 1 unit and its center at the origin of the coordinate plane. Points on the unit circle are related to periodic functions.
You can use the symbol θ for the measure of an angle in standard position.
Take Note Key Concepts: Cosine and Sine of an Angle
Suppose an angle in standard position has measure θ. The cosine of θ (cos θ) is the x-coordinate of the point at which the terminal side of the angle intersects the unit circle. The sine of θ (sin θ) is the y-coordinate.
