A cubic Bzier curve is a parametric polynomial curve given by: X(t) = (1 t) b + 3(1 t)tb + 3(1 t)tb + tb3 where b; are the control points. Suppose the control points are bo = (-1,0), b = (0, 1), b = (0,1), and b3 = (1, 0). Use de Casteljau's algorithm to find the coordinates of X(0.25), and check it with the polynomial equation above.
