[attach]113107[/attach] x^2 / a^2 + y^2 / b^2 = 1; a = semiasse maggiore = 4; b = semiasse minore = 2; x^2 / 16 + y^2 / 4 = 1; x^2 + 4y^2 = 16. F1 (- c; 0);  F2 = (c; 0) c = radicequadrata(a^2 - b^2); c = radice(16 - 4) = radice(12); F1 = [- radice(12); 0];  F2 = [+ radice(12); 0]. Ciao @michele-09

x^2/4^2 + y^2/2^2 = 1 x^2/16 + y^2/4 = 1 c^2 = a^2 - b^2 = 16 - 4 = 12 c = 2rad(3) F1 = (-c,0) F2 = (c,0)
