curvature of a circle of radius r is given by?
the reciprocal of the radius
the direction of the acceleration is the unit normal vector , which is defined by









































the plane containing the two vectors and is called the osculating plane to the curve at . the curvature has the following geometrical interpretation. there exists a circle in the osculating plane tangent to whose taylor series to second order at the point of contact agrees with that of . this is the osculating circle to the curve. the radius of the circle is called the radius of curvature, and the curvature is the reciprocal of the radius of curvature:

if the radius is fixed, then the parameter space would be reduced to 2d (the position of the circle center). for each point (x, y) on the original circle, it can define a circle centered at (x, y) with radius r according to (1). the intersection point of all such circles in the parameter space would be corresponding to the center point of the original circle.
