2. Then they must have they same set of eigenstates. 3. I calculate the Integral from this interval over the probability density.

Hi! I'm working on the same exercise as fkliment2000. I already got the eigenstates like Repetit said. But I have some more questions to answer, but i don't know how.. 1) Is cos(k*x) an eigenstate of both of these operators? (k is the wave number of this state, x is the position coordinate)...

Thanks for the answer!

Hi! How can I write the wave function of a particle in an infinite box (in the state n) as a superposition of the eigenstates of the momentum operator? the wave function is: PHIn(x,t) = sqrt(2/a) * Sin(n * PI/a * x) * exp(-i En/h * t) Thanks for your help!

Hi, sorry I made a mistake in the formula. It should be En = (n + 3/2) hw

Hi! I'm trying to calculate the degeneracy of each state for 3D harmonic oscillator. The eigenvalues are En = (N + 3/2) hw Unfortunately I didn't find this topic in my textbook. Can somebody help me?
