Hint: use gram-schmidt orthogonalization method

2.26 A vector space is described by the following basis: O -2 OAN V1 = VO = VA = 2 Find an orthonormal basis for this vector space. Suppose y = [1 2 3 4]'. a) Express y in terms of the new basis computed above. b) Express y in terms of the original basis set { v1, V2, V3, V4}
