Question:
a. Let {v1; v2,.......,vp} be linearly independent set of vectors in Rn that is not necessarily orthogonal. Describe how to find the best approximation to z in Rn by vectors in W = Span{v1; v2,.......,vp} without first constructing an orthogonal basis for W.
b. Let
Find the best approximation to z by vectors in Span {v1, v2} using part (a) and using the orthogonal basis found in Exercise 3 in Section 6.4. Compare.
Data From Exercise 3 in Section 6.4
The given set is a basis for a subspace W. Use the Gram–Schmidt process to produce an orthogonal basis for W.
