WebJan 11, 2024 · When the central angle formed by the two radii is 90°, the sector is called a quadrant (because the total circle comprises four quadrants, or fourths). When the two radii form a 180°, or half the circle, the sector is called a semicircle and has a major arc. Unlike triangles, the boundaries of sectors are not established by line segments. WebAug 21, 2024 · For example, if you’re trying to solve $\cos{π/3}$, you should know right away that this angle (which is equal to 60°) indicates a short horizontal line on the unit circle. Therefore, its corresponding x-coordinate must equal $1/2$ (a positive value, since $π/3$ creates a point in the first quadrant of the coordinate system).
