too bad you're not more popular, too bad education is so unpopular, this is worth diamond to us students, I wish I could give you more than my uttermost gratitude

THIS IS VERY BRILLIANT AND HELPFUL!! Thank you! I''l be having my final in the next 2 hours and I understand from your video only. Goodjob!

We don't have an e^(3x), we have e^(5x) and e^(-2x), so we don't have repetition.

I'm confused...I thought the Yp would have to be Axe^3x because we already have a constant times e^3x with 2e^3x and would have to multiply by another factor of x as to not have repetition. That's what I was expecting you to do after watching your other video, so now I'm lost. Help! PS- I love your DE videos! You are awesome!!!

what if we have exponential and polynomial at the left side of the equation how can we find the general solution?thank you sir

Oh, you're absolutely right. It makes total sense now! Thank you for the quick reply :)

isnt e^3x in the fundamental set of solutions? SO we cant use it?

Can you explain why in some examples when you have to find particular solution, you have to asume that y = A*x*e^(nx) and you just assumed y = A*e^(nx).
