Homework Help: Finding the normalization constant for a 1-D time independent wave function

  1. Oct 27, 2012 #1
    1. The problem statement, all variables and given/known data

    ψ(x)=A((2kx)-(kx)^2)
    0≤X≤2/k
    ψ(x)=0 everywhere else

    I need to find A

    2. Relevant equations

    ∫|ψ(x)|^2 dx=1

    so I know I need to evaluate it between 0 and 2/k

    3. The attempt at a solution

    My problem is do I square the whole ψ(x)? If some one could point me in right direction I would really appreciate it.

    Hello and welcome.

    Yes, as long as ψ(x) is a real valued function, then |ψ(x)|2 is just the square of ψ(x) (including the constant A).
