WebTrigonometric ratios can also be represented using the unit circle, which is the circle of radius 1 centered at the origin in the plane. In this setting, the terminal side of an angle A placed in standard position will intersect the unit circle in a point (x,y), where x = cos ⁡ A {\displaystyle x=\cos A} and y = sin ⁡ A {\displaystyle y=\sin A} . [35] WebA unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1. For a straight line drawn from the circle’s centre point to a point along the circle’s edge, the …
