but, and about the z component for example, if I do this in two coordenates, the answer will be zero, maybe is zero the solution, I do not know

Homework Statement Let e and f be unit vectors. Le = eL is the definition of the component of angular momentum in direction e. Calculate the commutator [Le,Lf ] in terms of e, f and L Homework Equations [A,B]=(AB-BA) The Attempt at a Solution we know that L=r x p, in classical mechanics, and...
