Webb10 apr. 2024 · Sin 180° and Sin 0° have the same value, which is zero. It is because 180° is in the second quadrant and the value of sine theta that exceeds 90° shifts to the cosine function. That is to say, Sin (90 + X) = cos X. Sin 180 can be written as: Sin 180 = Sin (90+90) = Cos 90. Since cos 90 = 0, we get. Sin 180 = 0.
