Web18 mei 2024 · Using a unit circle chart, get the value of sin 900°. Solution: Let us represent 900° in terms of 360° because the unit circle has 0°-360°. 900° is equal to two full 360° rotations plus an additional 180° rotation. As a result, 900° and 180° share the same trigonometric ratio. WebEvaluate sine and cosine values using a calculator. 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 = 1, we see that for a ...
