a) Starting with the canonical commutations for the position and momentum, work out the following commutators: [Lx], [Ly], [Lz], [L₂px]. [Lzpy] and [Läpz]- b) Use these relations to obtained [L,Lx] directly from the classical equation of the angular momentum. c) Evaluate the commutators [L,~²] and [L_,p²], where 7² = x² + y² + z² and p² =p²+p}+p².
