Equations related to circles
WebUse the standard form of a circle. (x−h)2 +(y−k)2 = r2 ( x − h) 2 + ( y − k) 2 = r 2. Identify the center (h,k) ( h, k), and radius r r. (x−(−2))2 +(y−1)2 =32 ( x − ( − 2)) 2 + ( y − 1) 2 = 3 2. The center is (−2,1) ( − 2, 1), and the radius … WebTo determine a circle completely, not only its radius (or curvature), but also its center must be known. The relevant equation is expressed most clearly if the coordinates (x, y) are interpreted as a complex number z = x + iy. The equation then looks similar to Descartes' theorem and is therefore called the complex Descartes theorem .
