(a) Compute the first-order correction to all energy eigenvalues of a particle in a square well in the region 0 ≤ ? ≤ L with added potential: ?(?) = ?_o? when 0 ≤ ? ≤ L/2 and ?_o (L − ?) when L/2 ≤ ? ≤ L.

(b) Using the given potential, use the variational theorem to compute an upper bound to the ground state using the trial function below

∅(?) = ?₁ (2/L)^1/2 sin ( ??/L ) + ?₂ (2/L)^1/2 sin ( 2??/L )

It is well known that the Lagrangian of a classical free particle equal to kinetic energy. This statement can be derived from some basic assumptions about the symmetries of the space-time. Is there any similar reasoning (eg. symmetry based or geometrical) why the Lagrangian of a classical system is equal kinetic energy minus the potential energy? Or it is just because we can compare the Newton's equations with the Euler-Lagrange equation and realize how they can match?
