= Solution

<Cyclic permutation> of the coordinates in the preceding <commutator> calculation gives the remaining <orbital angular momentum commutation relations>:
$$
\boxed{[\hat j_y,\hat j_z]=i\hbar\hat j_x,\qquad [\hat j_z,\hat j_x]=i\hbar\hat j_y.}
$$
Reversing the order of a <commutator> reverses its sign.
