WebLike all functions, the sine function has an input and an output. Its input is the measure of the angle; its output is the y -coordinate of the corresponding point on the unit circle. The cosine function of an angle t t equals the x -value of the endpoint on the unit circle of an arc of length t t. In Figure 3, the cosine is equal to x x.
WebA radian is a relative unit based on the circumference of a circle. As you know, radians are written as a fraction with a π, such as 2π/3, 5π/4, or 3π/2. Since the equation for the circumference of a circle is C=2πr, we have … WebUnit Circle. A unit circle has a center at (0, 0) and radius 1. In a unit circle, the length of the intercepted arc is equal to the radian measure of the central angle t. Let (x, y) be the endpoint on the unit circle of an arc of arc lengths. The (x, y) coordinates of this point can be described as functions of the angle.
