Complementary observables

  1. Dec 9, 2011 #1
    1. The problem statement, all variables and given/known data
    Are the observables corresponding to the d/dx and x^2 operators complementary?


    2. Relevant equations
    none


    3. The attempt at a solution
    I know that if the operators do not commute then their corresponding observables are complementary. I just dont know how to show mathematically that they dont commute.

    Use the commutator definition [A,B]=AB-BA to show if they commute or not.
