Determine if the following statements are true or false. Prove if it is true or give counter example if it is false. Let T be the linear operator on inner product space C². C?. If (i) T(x,y) = (2ix+ 3y,x- y) then T is self-adjoint. ii) If W is an orthogonal set consisting non-zero vectors in Rk, then W is linearly independent. ii) If S and T are self-adjoint operators, ST + TS is also a self-adjoint operator.
