    How to Calculate the Expectation Value of x^2 in Quantum Mechanics?

    Homework Statement I am given ψ(x), want to calculate <x^{2}>. Homework Equations \psi(x) = a\exp(ibx-(c/2)(x-d)^2) <x^2> = \int\limits_{-∞}^∞ \psi^*x^2\psi \mathrm{d}x The Attempt at a Solution Well, I normalized the wave function and found a = (\frac{c}{\pi})^{1/4}. So, the...
