    Let K be an nxn matrix and  a small number. Imitating
    .....
    valid for small x, it is natural to define
    ....
    Explain why this makes sense. Prove
    trace log = log det(I + K)
    Still with  small so that everything makes sense.
    Hint: What is I − K +2K2 − 3K3 + · · · ?
    Since this is an analysis problem, please be sure to be rigorous, and include as much detail as possible so that I can understand. Please also state if you are making use of some fact or theorem. Thanks!
