TRUE correct Explanation: Since the zero vector 0 is orthogonal to ev- ery vector in R n and any set containing 0 is linearly dependent, only orthogonal sets of non-zero vectors in R n are linearly indepen- dent. Consequently, the statement is TRUE . Ans: The orthogonal vectors must be linearly independent (we proved in class that orthogonal vectors are always linearly independent), and they will form a basis for the subspace W. Since there are nof them, W has dimension nand therefore must be all of Rn. B.
