Defining Sine and Cosine Functions Now that we have our unit circle labeled, we can learn how the \((x,y)\) coordinates relate to the arc length and angleThe sine function relates a real number \(t\) to the ycoordinate of the point where the corresponding angle intercepts the unit circleMore precisely, the sine of an angle \(t\) equals the yvalue of the endpoint on the unit circle of anThe product is (–2) × (–1) = 2, which is positive Any other product in Quadrant III will be positive also, so Quadrant III is not part of my answer In Quadrant IV, I'll pick, say, (3, –4) The product is 3 × (–4) = –12, which is negative Any other product in Quadrant IV will be negative also, so Quadrant IV is part of my answer(1) I (3) III (2) II (4) IV
