A question laws of the inverse

  1. Feb 29, 2008 #1

    that some how the ability for the matrix to be inversible
    connects to its dim Im

    can you say how it works in this question???

    I linked to a very specific section of that page, namely the one stating
    Now if you have some knowledge of linear maps and such (which I presume you do, or should have at least, because the book uses terms like kernel and image in the first place), the statement will immediately follow.
