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 … WebLearn the equation of a unit circle, and know how to use the unit circle to find the values of various trigonometric ratios such as sine, cosine, tangent. Also ... At 90º and at 270º the …
