Show that its squar integrable

  1. Oct 17, 2011 #1
    1. The problem statement, all variables and given/known data
    This is a physics problem but dont understand the math really

    2. Relevant equations

    ∫f*f =1

    3. The attempt at a solution
    I thought it would be f2=a(eix+ie-x2)*a(eix+ie-x2)
    but they have it as a*(e-ix-ie-x2)a(eix+ie-x2)

    Dont really know what the * mean in the y* usually i would do it what i did but that was for problems like f=e(-5+x) or somthing
