Thank you for your reply. I will take a look into the wiki link. :smile:

The question didn't give boundary conditions. But I think it should be x(0)=x0 and \dot{x(0)}=\dot{x}0.

I think it is perturbed.

Hi JJacquelin, Thank you for the help. I will follow this method to the rest.

Hi JJacquelin, Line 7 on your attached picture, I had a little different than yours. I had X^3 instead of X^2. I am still working on it. Please let me know. Thank you,

Hi JJacquelin Thank you very much for your help, I will try it and see if I could reach the result in that picture. Thank you again for helping me out.

Hi everyone, I need some help to solve this differential equation. The question states "Use the perturbation or multiple scale method to find the third-order approximate solution for the following system: diff(x(t), t, t)+w^2*x(t)*(1+epsilon*x(t)^2) = 0 " Currently, I am still...
