Just giving you prior warning …..
They’re next in the course and I dislike them even more than the stuff we’ve done before.

It’s OK, mv remembers the course on these like it was yesterday.

FWIW, SN, I recommend learning to use Laplace transforms. Convert any DE to an algebraic equation, solve that, then convert back to the original domain. It works on every DE I’ve encountered IRL, and is the best way I’ve ever seen for solving systems of DEs.

Yeah, but then you have to learn partial fractions, and no-one’s got time for that shit :)

I suspect that Bill will eventually get to LaPlace, the uni will just make him suffer through differential equations first.

For solving these numerically, the shooting method always works.

Not like you.

How come you didn’t require good evidence of brace position?
