6. For each of the statements below, State whether it is true or false, and Motivate your answer with either a proof, a reference to a definition or theorem, or a counterexample. S:= T:= (a) Both and are spanning sets for R3. (b) Let v1 Vk Vk+1,.Vn be vectors in a vector space V. Let S:={v1 V2., Vk) and T= {Vk+1 Vk+2.Vn}. If S is linearly dependent, then SUT is linearly dependent. (c) If A is a (3 x 3) upper triangular matrix such that one of the diagonal entries of A is zero, then the column vectors of A are linearly dependent.
