WebJun 14, 2024 · The angle (in radians) that t intercepts forms an arc of length s. Using the formula s = rt, and knowing that r = 1, we see that for a unit circle, s = t. Recall that the x- and y- axes divide the coordinate plane into four quarters called quadrants. We label these quadrants to mimic the direction a positive angle would sweep. WebDefinition of a Reference Angle Let θ be a nonacute angle in standard position that lies in a quadrant.
