Homework Help: Problem with normalisation, or should i say integration

  1. Mar 26, 2012 #1
    1. The problem statement, all variables and given/known data

    Consider the wave packet [itex]\psi(x)\equiv ψ(x, t = 0) = Ce^{i\omega x}e^{-\left|x\right|/2\Delta x}[/itex] where C is a normalisation constant.

    Normalise [itex]\psi(x)[/itex] to unity.

    2. Relevant equations

    3. The attempt at a solution

    I know the normalisation condition. My problem is when I have ...

    [itex]\left|C\right|^{2}\int e^{-\left|x\right|/\Delta x} dx = 1[/itex]

    Any help will be MUCH appreciated.

    Say delta x=x-x0

    Good thinking! But this makes the problem even harder . lolzz. because I have literally NO idea how to integrate such an expression!
