WebBecause the number 1 is called "the unit" in mathematics, a circle with a radius of length 1 is called "the unit circle". Once the hypotenuse has a fixed length of r = 1, then the values of the trig ratios will depend only on x and y, since multiplying or dividing by r = 1 won't change anything. Only the values of x and y will matter. 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 = t. ...
