Thank you very much! I'm studying for my Advanced Engineering Analysis Final and this really helped!

you teach so much better than my professor bless you

+Savage Lu Teachers on KZbin usually teach things because they enjoy doing that, whereas a lot of professors just teach because it's kind of part of their job, so it's often a pure routine to them without any real passion behind it.

At 8:15, the correct decomposition of the characteristic equation is (r - i * sqrt(|λ|)) * (r + i * sqrt(|λ|)), then the solution for the 3rd case is Φ(x) = A cos(sqrt(|λ|) * x) + B sin(sqrt(|λ|) * x).

OH MY GOD FINALLY SOMETHING THAT HELPS!

[@blancaroca8786]

just wondering if there is some connection between ODE seperability and PDE seperablity. They seem like completely different procedures.

Thank you sir, excellent video!

thank you for the excellent video

Why did you opt to set the second ODE equal to zero but not the first? How do you make the determination of when to set it equal to 0?

[@may83195]

They can both be equal to 0 when you rearrange it like that, but he's solving the second order ode first
