- Homework Statement:
- I need to use the second order pertubation theory to estimate the lowest order eigen value. I'm not sure where to even start in solving this problem. What would be the steps I need to take in order to solve?

- Relevant Equations:
- I was given an integral that I can use, but as I just want to know the steps to solve the problem, haven't listed here.

Not sure where to start!
