1. The problem statement, all variables and given/known data find the zero point energy of particle of mass m in one dimension under: V(x)=(1/2)kx^2 for x>0; infinity for x<0 2. Relevant equations ?? 3. The attempt at a solution I'm completely lost :( I took a similar approach to deriving eigenvalues for a particle in a box but that didn't make sense to me... Any starters?
