Physical Intrepretation of cofactors

  1. Jun 22, 2011 #1
    Is there any physical significance of the matrix terms such as cofactors and minors? I state that this is used for finding the inverse but that is rather an abstract concept and does not motivate the student . Is there any real life applications of these terms.

    Did you come up with anything on this question yet?

    I'm also curious about a geometric interpretation of cofactors and minors. A determinant can be interpreted as some kind of area or volume. If we have a 3x3 determinant expanded in terms of cofactors and minors, it is written as a sum of terms. Each term (apparently) can be interpreted as a volume. The minors represent areas and the cofactors might represent sides. At the moment, I'm not patient enough to sit down and draw the geometry of a particular example. I wonder if some diligent geometer has already done that for us.
