WebSo: x = cos t = 1 2 y = sin t = √3 2. Analysis: Because the unit circle has radius 1, we can think of both the x - and y -coordinates as ratios of a right triangle, if angle t is acute. … WebIn the unit circle approach, we just use the properties of coordinates in the \(xy\)-plane, remembering that the \(x\)-coordinate corresponds to cosine, and the \(y\)-coordinate corresponds to sine. So, in the first quadrant, both coordinates are positive, so sine and cosine must both be positive. This means that tangent is also positive.
