Example 6.  Find the Bézier curve which starts at [Graphics:Images/BezierCurveMod_gr_243.gif] and ends at [Graphics:Images/BezierCurveMod_gr_244.gif] which has the control points [Graphics:Images/BezierCurveMod_gr_245.gif] and [Graphics:Images/BezierCurveMod_gr_246.gif], respectively.
Use Bernstein polynomials.  

Solution 6.

Formulate the Bézier curve as linear combinations of Bernstein polynomials and call it  [Graphics:../Images/BezierCurveMod_gr_247.gif].
