Cosine of 225
WebJun 14, 2024 · We know that cos t is the x -coordinate of the corresponding point on the unit circle and sin t is the y -coordinate of the corresponding point on the unit circle. So: x = cos t = 1 2 y = sin t = √3 2. Try It 2.2.1. A certain angle t corresponds to a point on the unit circle at ( − √2 2, √2 2) as shown in Figure 2.2.5. WebThe sin of 225 degrees equals the y-coordinate (-0.7071) of the point of intersection (-0.7071, -0.7071) of unit circle and r. Hence the value of sin 225° = y = -0.7071 (approx) ☛ Also Check: sin 2 degrees sin 150 degrees sin 50 degrees sin 6 degrees sin 585 degrees sin 47 degrees Examples Using Sin 225 Degrees
