# Can elliptic arc be represented by quadratic Bezier curve?

Can elliptic arc (defined as part of an ellipse, with extent not bigger than 90 degrees) be represented by quadratic Bezier curve?

I would call that an "elliptical arc". An elliptic curve is something completely different. –  Rahul Nov 25 '10 at 4:26
@Rahul Narain - Thanks! –  Rogach Nov 25 '10 at 4:29
A rational quadratic, yes, but I'm pretty sure not a quadratic... –  Ｊ. Ｍ. Nov 25 '10 at 4:30
Also, quadratic Bézier curves can only represent parabolas. To represent elliptical arcs and other cubic sections exactly, you need rational functions, as J.M. mentioned in your previous question. –  Rahul Nov 25 '10 at 4:33
