6. Suppose you have two operators A^=dxd and B^=x2. and a function f(x). Determine A^B^f(x) and then determine B^A^f(x). What is the value of A^B^f(x)B^A^f(x) ? Hint: If you are hving difficulty using the arbitrary function f(x), try substituting in an expression such as f(x)=sin(2x). Just remember that if two operators commute, it should be true for all functions
