(a) Compute the first-order correction to all energy eigenvaluesof a particle in a square well in the region 0 ≤ ? ≤ L with addedpotential: ?(?) = ?o? when 0 ≤ ? ≤ L/2 and ?o(L − ?) when L/2 ≤ ? ≤ L.
(b) Using the given potential, use the variational theorem tocompute an upper bound to the ground state using the trial functionbelow
∅(?) = ?1 (2/L)1/2 sin ( ??/L ) +?2 (2/L)1/2 sin ( 2??/L )
