Thank you for your advice! Do think It's better to switch right in the middle of the major or at least finish it ? If I switch now I have a minor in physics. Thanks again, Machete

haha lol thanks :P amd another question : we always use u = ln (x) for Euler's type ODE ?

damn it! all terms cancel out when I got with y(u) = Ae2u+ Bue2u I'm going to try again tomorrow. thanks again!

First of all, thank you all for you answers. Yes, I know that all I need from now on it is only A's, with few B's. I'm trying my best to achieve it, and to answer your question, it's more the love of physics rather than just the idea to be a physicist. Let's say it doesn't get better, what...

Thank you very much :D I'm trying it right now

Hello everyone! Here is a short (?) introduction of myself, by myself : https://www.physicsforums.com/showthread.php?p=1940774#post1940774 So I'm currently doing a Major in physics, I'm having a hard time right now but hopefully I will be successful. Here are my questions : Will a minor...

Hello guys! Well, where to start? First I want to say that I'm really happy to find a forum like this, I've spend like 2 hours reading the career and academic guidance section, and I realized that I have a lot of questions myself. Before I start I apologize for my future grammatical mistakes...

Hello everyone! I'm trying to solve 2 questions for my assignment on homogeneous ODEs I can solve ODE's with variation of parameters and with the method of undetermined coefficients, but these 2 methods seem useless when the coefficients are not constant : (x^2)y" - 2xy' -54y = 0 and...
