Griffiths Intro to QM 7.11 (3rd edition) solution: ground state energy of H using Ae^(-br^2)

In this video, I will show you how to solve Griffiths Introduction to quantum mechanics problem 7.11 (3rd edition), in which we want to find an estimate for the ground state energy of Hydrogen using the variational principle and a trial function
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.
