$\vec{A} = 5\hat{x} + 4\hat{y}$

One-dimensional time-dependent Schrodinger equation of a particle of mass $$m$$ is  $i\hbar \frac{d \Psi(x,t)}{dt} = - \frac{\hbar^{2}}{2m} \nabla^{2} \Psi(x,t) + V(x) \Psi(x,t)$ where $$\Psi(x,t)$$ is the wave-function representing the particle and $$V(x)$$ is assumed to be a real function representing the potential energy of the particle.
