    What makes Eigenvalues and Eigenvectors important and how were they developed?

    I'm currently taking linear algebra and it has to be the worst math class EVER. It is extremely easy, but I find the lack of application discouraging. I really want to understand how the concepts arose and not simple memorize an algorithm to solve mindless operations, which are tedious. My...

    Is there a relation between the eigenvalues of L^2 and Lz^2?

    I'm trying to show the relation between L^2 and Lz where L is total angular momentum and Lz is the z component. Given f is an eigenfunction of both L^2 and Lz L^2f = [lamb] f Lz f = [mu] f and L^2 = Lx^2 + Ly^2 + Lz^2 then <L^2> = < Lx^2 + Ly^2 + Lz^2> = <Lx^2> + <Ly^2> + <Lz^2>...

    What is the relationship between eigenvalues and the metric in linear spaces?

    the signature of a metric is often defined to be the number of positive eigenvalues minus negative eigenvalues of the metric. this definition has always seemed a little suspicious to me. eigenvalues are defined for endomorphisms of a linear space, whereas the metric is a bilinear functional...
