(part 6)Quantum mechanics by zettli chapter 9 problem 9.3

Description Text:
In this video, I provide a detailed, step-by-step solution to Problem [Number] from Chapter 9 (Approximation Methods for Stationary States) of Nouredine Zettili's Quantum Mechanics: Concepts and Applications. This problem focuses on Time-Independent Perturbation Theory, specifically addressing [mention if it is Non-Degenerate or Degenerate] cases.
Key Concepts Covered:
Identifying the Hamiltonian: Breaking down
.
First-Order Corrections: Calculating energy
and state
