Ey 4chan whats your opinión about the difficulty this exam of linear álgebra in a scale of 1 to 10 (the exam is in spanish)
Cual es su opinión de la dificultad de este examen de álgebra lineal en una escala del 1 al 10

Why do Iberians and their progeny have such a high goddamn opinion of themselves?

Let me make something abundantly clear to you OP:

You're standards are not high, they're lower than average even, you have such a high dropout rate because you're genetically retarded, not because your work is more difficult.

Pretty much no proofs, just solve problems.

Yeah, that's nothing.

>>7202784
Then you didn't learn anything in linear algebra. Because that's as basic as you can get.

Unless, of course by "linear algebra" you mean you took a intro to matrices class and thought it was linear algebra, because they insisted on calling it that.

it's obvious it's an engineering class, the problems are piss-easy plug-chug, no proofs

you still can't do any of it because you're retarded

the only constraint for which i gave this a 4/10 is because of the time vs amount of questions. but if you can't do them because of difficulty, man, wow

My linear algebra was proof based and the lecturers were profs from the math department.

I wish people would realize that it's only the grade inflated unis that has shitty _ for engie classes, at proper unis you take the same courses as math students.

No I meant my class had no "If A = [a,a1,a2,...an] then Ae_n=] bullshit
that is a proof
and it is for math majors only

it's like saying you can't use your refrigerator unless you can explain everything it's doing using physics. not conceptually but actually using numbers.

look buddy all i need to know how to do is solve linear systems with matrices and calculate determinants

everything else should be saved for mathniggers. they should not even have a linear algebra course for anyone but physics and math majors because the extent to which all other majors would use it is what i just mentioned and can be taught in maybe 2 weeks.

look man, me and almost every other person on earth is never going to have to solve something like that. If the word "subspace" is in a problem, it should be encountered only in a math major course. Same with vector spaces. Same with any space except maybe eigenspaces.

pretty much any problem that contains the word "space" and isn't referring to an eigenspace is going to be a proof and should only be in math major courses.

Holy shit, you are retarded.

Row reduction and determinants isn't even linear algebra, it's fucking highschool matrix algebra.

OP, you're a fucking retard. I'm also a student of this shitty university, and the engineering math courses don't even deserve to be called so. It's a shame math majors are forced to take them, but I guess the directors would rather spend money on engineers like you than on a decent math education.

>>	Anonymous Sat Apr 18 19:10:25 2015 No.7203636 >>7203621 That's just the dumbed down engineering part of it, though. The pure math stuff isn't so bad, but still far behind any decent university. It doesn't matter too much though, the actually motivated students will just study on their own anyways.
