On the unit circle what is sin
WebThe unit circle can be used to find sin and cos values for angles between 0 ° and 360 ° or 0 and 2𝜋 radians. The x-coordinate of points on the circumference of the unit circle … WebEquation of a Unit Circle. The general equation of a circle is of the form ( x − a) 2 + ( y − b) 2 = r 2, where the center of the circle is (a, b) and the radius is r. A unit circle in the x-y plane is formed with a center at origin (0,0) and radius 1. Thus, the equation of the unit circle on an x-y plane is x 2 + y 2 = 1.
