Homework Statement
Show that ##|l, m\rangle## for ##l=1## vanishes for the commutator ##[l_i^2, l_j^2]##.
Homework Equations
##L^2 = l_1^2 + l_2^2 + l_3^2## and ##[l_i^2,L^2]=0##
The Attempt at a Solution
I managed to so far prove that ##[l_1^2, l_2^2] = [l_2^2, l_3^2] = [l_3^2, l_1^2]##. I know that for ##l=1##, I have ##m=-1,0,1## but I'm not really sure how to proceed from here though. Any tips?
