Thanks for your reply - it helped me out of my blockade. I was too fixed at the implicit characterisation of orthogonal points to P by the equation P' ( x - P ) = 0. You are right, exept a typo in the sign for z in your formula. Points or vectors, that is an old discussion. "Vectors" are...

I have a given point (vector) P in R^3 and a 2-dimensional linear subspace S (a plane) which consists of all elements of R^3 orthogonal to P. The point P itself is element of S. So I can write P' ( x - P ) = 0 to characterize all such points x in R^3 orthogonal to P. P' means the transpose...
