WebIn the concept of trigononmetric functions, a point on the unit circle is defined as (cos0,sin0) [note - 0 is theta i.e angle from positive x-axis] as a substitute for (x,y). This is true only for first quadrant. how can anyone extend it to the other quadrants? i … WebTrigonometrical functions of any angle: Let A be a given angle with specified initial ray. We introduce rectangular coordinate system in the plane with the vertex of angle A as the origin and the initial ray of angle A as the positive ray of the x -axis. We choose any point P on the terminal ray of angle A.
