    phi in spherical coordinates should be in this notation arctan(y/x) no arctan(y/z)

    Note: two matrices that do not commute can have a common eigenvector
    [x,p] = ihbar is a particular case

      How can they?
      I mean unless you use the commutator factor i h bar and multiply with it the eigen functions won't be Same? No??

    Here I am, a PhD student, taking online undergrad courses. I hope my department does not see how bad of an investment they have made

    why the questions asked by students are omitted from the videos?? there are lot to learn from those questions too

    How to get L^2 is that formidable formula? I still cannot figure out.

      It's better to review this problem in a linear algebra way. You just need to calculate the cross product of two vectors which are in the same plane. Like Lx equals the r vector( in the plane zy) multiply( cross product) the p vector(in the plane zy), fairly easy.

      zp H from the classical definition L=rxp
