Can someone explain me if I am retarded or not?

It can be explained that when you study you study to understand. You can pass linear algebra with no inherent understanding by memorizing all methods of solving. At least on my uni, if you were to dig in and actually understand the background to every method it becomes harder and our profs doesn’t want to fail 80% of their students.

Anyone else's prof did this?

You have attention and or memory and or conceptual procesing problems. Also maybe you hate having dumb teachers write some shit down a couple times while they look at a book and give you no historical or theoretical backround information then tell you to go do what they did fifty times in a row when you get home.

Close I inhibit symptoms people attribute to adhd and all of my math teachers were terrible turning the subject into a braindead act of repetition divorced of all context so I just cut classes. I picked it up in university when I went in my mid twenties and I was surprised in how enjoyable it was when in my whole previous school career math class was a extremely boring dreaded part of the day

The introductory linalg is probably a lot for engineers or science students. Like year 1 engineers dash so fast in my school, their calculus reaches Laplace and Fourier transforms and shit. It's all about application of these algorithms, calculate calculate. Physics students do it in second year or the first if you are daring enough. It's a different mindset altogether.

It's really worth it though. I've taken both an engineering LinAlg which was essentially a course in Gauss-Jordan reduction and a pure math one which was roughly based on Hoffman-Kunze's book, and the latter was definitely more illuminating and fun (admittedly that's my idea of fun); I never had any idea what I was doing and why on the engy one.

ive noticed people are usually good at linear algebra and continue to abstract algebra
or they are good at analysis and continute to do real analysis , PDEs and so on
the ones that are good at both tend to be usually people who did math olympiads and so on

Is your prof retarded? The theorem is the foundation of all linear algebra, almost every other theorem depends on it.

If your real analysis class was that easy then it was a shitty analysis class

I think he's probably referring to the proof, since it's a fairly intuitive idea, but takes considerable work to explain why it's true.

They should really have a separate linear algebra course for CS/engineering/physics/economics which just covers the basics and the applications. CS ad eng fags drag down all the 2nd and 1st year math courses.
>>11546816
Doesn't it make sense that way? If he's consistently using something, then you will probably pick it up regardless of the initial explanation.
