1. A particle of mass is confined in a potential given by () =

4 where is a

positive constant. Use the variational method with a trial wave function given

by () = 2 where is a

normalization constant and is a

real, positive parameter to estimate the ground-state energy for this system.

Show all math for full credit.

2. A particle of mass is confined in a one-dimensional box of length with a potential () = 2 for 0 < < and() = everywhere else. Use perturbation theory to the particle-in-a-box wave function solution to find the first-order energy correction to (a) the ground-state energy and (b) the first excited-state energy.1.
