# I Superposition states

Hi. I just want to check that I understand the following. If I have a general superposition of wavefunctions satisfying the TDSE then that superposition also satisfies the TDSE. But that superposition only satisfies the TISE if the energies are degenerate because the TISE is an eigenvalue equation.
Have I got it right ?
Thanks

I can assure you are correct and I don't even know what TDSE means.

TDSE=time-dependent Schrödinger equation, and the statement in #1 is correct.
