I could probably help if I had like a textbook to read and refresh my memory on this kind of stuff but I don't. So if you have some kind of chapter on this section or something that'd be cool, but like not pictures I need like pdfs or something to read otherwise it'll take forever and I'm not that patient lol

10. Mimi_x3

anyway what is the epsilon doing

11. Mimi_x3

is it a constant

12. Mimi_x3

or some mathematical thingy that i dont know about

13. Astrophysics

I think it's for nonlinear oscillations $F(x) \cong -kx+\epsilon x^3$ where epsilon is usually a small quantity

14. Astrophysics

So really if epsilon > 0 this means the force is less than the linear term, and if its <0 then the force is greater
