WebSimplify expressions using the even-odd properties and periodic properties. 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 =rt s = r t, and knowing that r =1 r ... WebJan 13, 2024 · The coordinate points where the measure of a specific angle hits the circle gives us our sine and cosine values. For example, with a ray coming from the angle 60 °, the point that ray hits the unit circle is at ( 1 2, 3 2). The x -coordinate gives us our cosine value for that angle, and the y -coordinate gives us our sine value.
