We present a trigonometric scheme to approximate a
circular arc with its two end points and two end tangentsunit
tangents. A rational cubic trigonometric B&eacute;zier curve is constructed
whose end control points are defined by the end points of the circular
arc. Weight functions and the remaining control points of the cubic
trigonometric B&eacute;zier curve are estimated by variational approach to
reproduce a circular arc. The radius error is calculated and found less
than the existing techniques.
