61 Given column vectors (a) Prove that ss, and s, are orthogonal. (b)Are they orthonormal? If not, normalize them to create a transformation matrix of orthonormal vectors. (e) Using the result of (b), write an orthog transformation matrix for so, s, and s (d) Compute the transform of column ve f = [3 -6 5]. (e) Compute the inverse transform of the in (d).
