Example 6.  Find the Bézier curve which starts at [Graphics:Images/BezierCurveMod_gr_195.gif] and ends at [Graphics:Images/BezierCurveMod_gr_196.gif] which has the control points [Graphics:Images/BezierCurveMod_gr_197.gif] and [Graphics:Images/BezierCurveMod_gr_198.gif], respectively.
Use Bernstein polynomials.  

Solution 6.

Formulate the Bézier curve as linear combinations of Bernstein polynomials and call it  [Graphics:../Images/BezierCurveMod_gr_199.gif].
