This is another fantastic lecture on second order systems.

how he get the matrix K from the mass spring system? A1, A2 are scalars or vectors, or matrices?

Had the pleasure of sitting in his lecture ... smart as hell and super funny. Rip gil!

Why are the stiffness matrices K symmetric exactly..? Did I miss the part where he explains or is it because it comes from physics and hard to explain in a short video?

Why did Strang not include the b(sin(ω)) components in the answer for the example?

It wasn't really clearly explained how there is 6 solutions.<br>Shouldn't there be 3 for the 3-mass problem? Since there are 3 eigenvectors.<br><br>I know he should be right. But what is the logic?

Oh, Gilbert Strang is such a smart guy. No, This video is totally unclear. Where the K/S matrix come from? How do I get those numbers inside the matrix?
