    Problem to Normalize a wave function

    Homework Statement To find the stationary states and the corresponding energies, I need to normalize the following equations: X(x)=A_x sin(\frac{n_x\Pi}{a}x) Y(y)=A_y sin(\frac{n_y\Pi}{a}y Z(z)=A_z sin(\frac{n_z\Pi}{a}z Because of their similiraty, these value of the normalize...

    Is the wave function normalized?

    Homework Statement The ground state wave function for the electron in a hydrogen atom is: \psi(r) = \frac{1}{\sqrt (\pi a_o^3)} e^\frac{-r}{a_o} where r is the radial coordinate of the electron and a_o is the Bohr radius. Show that the wave function as given is normalized...
