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

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
