Consider the plane am + by + oz 2 O. a) Describe how you would use the SVD to find orthogonal basis vectors for the plane. b) How many basis vectors are required to express a point on the plane? c) Find the point on the plane that is closest to (a, )6, '7) note that this corresponds to an orthogonal projection onto the plane. Hint: How can we express this problem in terms of projection onto an orthocomplement of a subspace of a matrix A
