Science talk:Math Exam Resources/Courses/MATH152/April 2016/Question A 24

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 $D$ 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 $VD$ should be $DV$ instead.

Best,

Brian

I think what the matrix V and D mean should be mentioned in the solution. Also, as Brian mentioned, that could be a better hint. But I am not sure about how justification for c) and d) can be improved....

Aside from this, I hope all mathematical expressions are in the math mode.
