Consider the vectors u = (6, 2, 4) and v = (1, 2, 0) from
Chapter 5, Problem 5.2.101(choose chapter or problem)
Consider the vectors u = (6, 2, 4) and v = (1, 2, 0) from Example 10. Without using Theorem 5.9, showthat among all the scalar multiples cv of the vectorv, the projection of u onto v is the vector closest touthat is, show that d(u, projvu) is a minimum.
