WebFinding Function Values for the Sine and Cosine. To define our trigonometric functions, we begin by drawing a unit circle, a circle centered at the origin with radius 1, as shown in Figure 2.The angle (in radians) that t t intercepts forms an arc of length s. s. Using the formula s = r t, s = r t, and knowing that r = 1, r = 1, we see that for a unit circle, s = t. s …
