High Quality Content by WIKIPEDIA articles! In geometry, a circular algebraic curve is a type of plane algebraic curve determined by an equation F(x, y) = 0, where F is a polynomial with real coefficients and the highest-order terms of F form a polynomial divisible by x2 + y2. More precisely, if F = Fn + Fn?1 + ... + F1 + F0, where each Fi is homogeneous of degree i, then the curve F(x, y) = 0 is circular if and only if Fn is divisible by x2 + y2. Equivalently, if the curve is determined in homogeneous coordinates by G(x, y, z) = 0, where G is a homogeneous polynomial, then the curve is circular if and only if G(1, i,0) = G(1, ?i,0) = 0. In other words, the curve is circular if it contains the circular points at infinity, (1, i ,0) and (1, ?i, 0), when considered as a curve in the complex projective plane.
