Homework Help: Another doozie

  1. Nov 13, 2011 #1

    Consider the one-dimensional, time-dependent wave function for infinite motion: (x,t) = Ae–a|x| e–it where A, a, and  are positive real constants. What are: (a) normalization constant A, (b) the quantum-mechanical expectation value of coordinate x, (c) the quantum-mechanical expectation value of x2, and (d) the quantum-mechanical expectation value of the square of momentum ^p2

    They look like they are straightforward to integrate... what is your problem exactly?
    Do you not understand what a normalization constant is, or how to calculate it, or did you get stuck in the integration, or ... ?
