Compute the Poisson bracket of any components of position or momentum with any component of angular momentum. Use the Poisson bracket representation as derivatives with respect to canonical coordinates and momenta. You might find it useful to write \(L^{i}=\varepsilon^{i j k} x^{j} p^{k}\), and use identities involving the totally antisymmetric tensor \(\varepsilon^{i j k}\).
