1. The problem statement, all variables and given/known data

Hello,

I need some things clarified before I can do my homework. They have to do with the adjoint operator. Say I have an operator P and its adjoint is P(dagger). I noticed that the complex conjugate of the adjoint gives back the operator. Does that mean the adjoint is just the complex conjugate?

No, that's not true. If you represent the operator as a matrix, you'll find the adjoint is the conjugate of the transposed matrix. It's not simply the conjugate.
