So P and Q satisfy the given relation...this means that PQ-QP=Q? Is this the correct expression I should be using to evaluate the eigenvalues?

Correction: The two operators P and Q satisfy the commutation relation [P,Q]=Q. It doesn't say that they commute but that they satisy the relation. How else can they satisfy the relation if they don't commute?

Homework Statement Suppose that two operators P and Q satisfy the commutation relation: [P,Q]=P. Suppose that psi is an eigenfunction of the operator P with eigenvalue p. Show that Qpsi is also an eigenfunction of P, and find its eigenvalue. Homework Equations The Attempt at a...
