LECTURE 5: VECTOR GEOMETRY : REPRESENTATION OF PLANES

5.3 Minimum distance from a point to a plane I Find the minimum distance, d, from point P with position vector p, to the plane defined by (r a):n^ = 0 I Consider vector (p a) which is a vector from the plane to the point P I The component of (p a) normal to the plane is equal to the minimum distance of P to the plane. i.e. d = (p a) :n^ ................
