# Given a radius, calculate Bezier curve

For a given radius, theta, and position, can you calculate a Bezier curve?

Perhaps if you give the definition of Bezier curve. –  AD. Nov 29 '10 at 21:28
Bézier curves cannot represent circles; they can approximate them however. Rational quadratics are needed here. –  Ｊ. Ｍ. Nov 29 '10 at 23:10
@J.M...can you please elaborate? –  Elpezmuerto Nov 30 '10 at 18:03

In section 2.11 on p. 27 of the following there is a description of how to create a bezier curve that exactly represents an arc.
