You can just shove an icepick through your eye and wiggle it around a bit

>3 examples

itll take more than 3 to learn a topic anon... practice more

Learn about lie groups and you will become redpilled.

hmm. it's after spring break. that means you must be at the part where you find the roots of a characteristic equation (cauchy-euler).

We have the weirdest class setup. 6 hour lectures in large auditoriums every 2 or 3 weeks. Last semester we had 20-30 person classrooms with 3 hour lectures 2 or 3 times a week. Because of an injury where I was hospitalized for two weeks, I've missed crucial parts of the curriculum and at the moment have no chance of catching up. My fault, undoubtedly, but still feeling hopeless.

Not amerifat, try again.

You're a brainlet. Don't need to be in a lecture to learn shit. It is your fault, indeed, for not getting off your ass at that moment and reading and doing practice problems.

Search "Elementery Differential Equations", by William F. Trench. It is a pretty good practice book to read alongside your textbook.
The methods may be slightly different than what your prof expects, but whats important is to recognize how he derives those techniques and applies them.
With enough dedication, and practice, you can hopefully start killing those tests.

Good luck anon

Elementary**** jesus, sorry

No anon, you must kill yourself immediately.

No wonder. In differential equations, you need to know the answer beforehand and to show that it fits.

what did he mean by this

Try V.I. Arnold's "Ordinary Differential Equations". Nicely written with lots of examples, suitable for beginners.

I once skimmed through a book in the library that said something along the lines of "something something lie groups... something something generalization of differential equations." Apparently, all of the seemingly disparate techniques for solving differential equations can be unified. Regrettably, I know nothing about lie groups, so I didn't understand a lick of it. (Of course, it's possible that I'm retarded and saying something that pretty much everybody knows)
