Every time a proof exercise comes out, you can always prove it with the content of the past 3 chapters AT MOST. Usually with just the content if that chapter you will have enough to prove it.

If you stumble upon one of this and cannot prove it then it is a good indicator that the topic of the book is way beyond your intelligence and should drop it for a book of the same topic but aimed at engineers or bio majors.

You're reading a text book, not a reference book. You're supposed to learn, not to just find the solution for something you were looking for.

books for engineers are way more complete than the others.

every fucking time gets me

>>8152013
literally every professor on the planet does this
All 3 of my professors did this at least twice a month

>>8152013
do you mean they mentally check if it trivial by mumbling to themselves for 10mins?

Fucking hate this. Critically looking at proofs is literally one of the skills they're supposed to be teaching yet if you raise your hand you'll be laughed out of the room

Stop being a whiny cunt, it's all on math overflow and stack exchange anyway.

>>8152013
this can't actually happen. I've had professors lose it while proving something... A lot. But never claim triviality then fucking it up.

>>8153895
fuck me I"m studying integrable systems in classical mechanics by perelomov right now and that cunt just does this non stop. REEEEE

>>8153895
They're teaching you the motivation.

How do you think people came up with the shit in the first place? They had some motivation, then applied some math to solve the problem. Not the other way. You're never going to learn how to do it on your if you don't understand this thought process.
