Unclear hint and remarks about solution | 1 | 07:33, 24 March 2018 |

Hello,

For question MATH152/April 2016/Question A 24, the hint given is unclear (perhaps mention how the values given for V and D can be used to answer the question). Assuming that stands for the diagonal matrix obtained after diagonalizing the input, I have the following thoughts. It seems that the justification for c) and d) can be improved on by simply looking at the entries of D, and the matrix product should be instead.

Best,

Brian
