if it found itself confined to the interior of a box, or attached to the end of a spring, or circling around a proton - we have to put in the Equation how V depends on the coordinates. If you put ...if it found itself confined to the interior of a box, or attached to the end of a spring, or circling around a proton - we have to put in the Equation how V depends on the coordinates. If you put this into Equation ??? (all you have to do is to note that ∇2Ψ=χ∇2ψ and that Ψ=ψχ), you find that the time-independent part of Schrödinger's Equation satisfies
