    Undergrad Consisity of non-homogenous systems of linear equations

    Well, you I meant the values of the coefficients. To be more clear, the question was I encountered was: ...list of systems goes here.. I guess I'm allowed to calculate the determinant after all as it doesn't solve the system by itself.. Well, I read this on an online preview of some book...

    Undergrad Diagonalizable Matrices & Eigenvalues

    Ok I got your point...I think the question should be now, how to check whether a matrix is diagonalizable or not? A theorem I've encountered in my textbook: and somewhere else I read this is sufficient to prove a matrix is diagonalizable but not the other way around.. that's why I posted the...

    Undergrad Consisity of non-homogenous systems of linear equations

    Consistency of non-homogenous systems of linear equations Hello, Is it possible to find out if a non-homogenous system of linear equations has: - Single Solution. or - Infinite Solutions. or - No Solutions. Without applying any methods/rules ( Such as Gauss, determinant..etc), just...

    Undergrad Diagonalizable Matrices & Eigenvalues

    Hello, Is it sufficient to determine that a nXn matrix is not diagonalizable by showing that the number of its distinct eigenvalues is less than n? Thanks for your time.
