dbp:proof	Here the Schrödinger equation reads Expanding the dot product and dividing by yields To remove the time dependence from the problem, the wave function is transformed according to . The time dependent Schrödinger equation becomes which after some rearrangement yields Evaluating each term on the right hand side of the equation The equation now reads which by Euler's identity becomes (en)
