Homework Help: Position/momentum representation and probablity density

  1. Sep 7, 2012 #1
    Hey guys,

    I have been trying to figure out the following problem but I have been having trouble working out the easier way to do it.

    I don't see how I can use the hint, "x is ihbar d/dp in the momentum representation".

    I assume that the more difficult way is to actually evaluate the Fourier integral and then take the absolute value squared of the result.

    Is there a shorter/simpler way to find the probability density of the momentum?

    Thank you,
