Solving Griffith's problem 6.1: First order correction of energy levels of ISW with delta bump

In this video I will solve Griffith's problem 6.1 as it appears in the 3rd edition of the book. I will determine the first order correction of energy levels of the infinite square well with delta bump. My name is Nick Heumann, I am a recently graduated physicist. I love to teach physics, so I decided to give YouTube a try. English is not my first language, but I hope that you can understand me well enough regardless. ▬ Contents of this video ▬▬▬▬▬▬▬▬▬▬ 00:00 Introducing the problem 01:00 Setting up the problem 01:30 Inserting the expressions into the equation 02:51 Solving the integral 04:55 Checking case for odd "n" 05:47 Checking case for even "n"
