Homework Help: Differntial of wave equation solution

  1. Apr 5, 2010 #1
    1. The problem statement, all variables and given/known data

    consider the differential d²ψ(x)/dx²=k²ψ(x); for which values of a is the equation e^(a*x) is a solution to the above equation.

    2. Relevant equations



    3. The attempt at a solution
    I have been working on this problem but I do not know how relate the 2 equations, or if I should use the Schrodinger equation. Any help is greatly appreciated.

    You may encounter some more help if you post this under the right name. This is probably more quantum mechanics than it is introductory physics. and Is psi(x) = e^(a*x)?
