Question 2. The set [1 = {u + tv | te R} represents a line that passes through point u e R" and has direction ve R", v 0 (for any t, the point u + to is on the line [1). Similarly, the set 62 = {w + sz | s ( R) represents a line that passes through point we R" and has direction z ( R", 2 0 (for any s, the point w + sz is on the line [2). We are interested in finding the minimum distance between the lines [ and Cz where the measure of distance is the Euclidean norm. (a) Formulate the minimum distance problem as a least squares problem. (b) Find a solution of the above problem in terms of u, v, w, 2. Assume that v and z are orthogonal, Le., v z = 0
