The second means that the tangent vector at u = 1 is in the direction of Pn - Pn-1 multiplied by n. Therefore, the last leg in the indicated direction is tangent to the Bézier curve. The following figures show this property well.
Webthis vector tangent to this curve, but also to any vector, I can draw that tangent to my surface. So, what does that mean? Well, that means the gradient is actually perpendicular to the tangent plane or to the surface at this point. So, the gradient is perpendicular.
