6.4 Best Approximation; Least Squares

6.4 Best Approximation; Least Squares. Theorem 6.4.1 Best Approximation Theorem. If W is a finite-dimensional subspace of an inner product space V, and if u is a vector in V, then proj W u is the best approximation to u form W in the sense that ? u - proj W u ? ? ? u - w ?
