Try Algebra by Lang, I think that would be a more appropriate comprehensive and reader-friendly text for a second course in Algebra.

Yeah I was thinking of using that one, but I wasn't sure if it was good for what I was doing. I'll check it out.

Lang is a meme.

I just want an Algebra textbook I can refer to, I'm not going to learn everything out of the book.

Pure math books about algebra like Lang begin way way different than college algebra.

>>10093970
It's shit. Read a precalculus textbook.

>>10093970
This one here is pretty much 10th grade level like algebra 2 in your town.

>>10094037
is there even any difference between algebra 2 and precalc? I remember when I took them in high school that I learned nothing in precalc because it was just a repeat of the year before.

>>10094015
Lang IS "college" "algebra."
What fucking college are you talking about?

>>10094119

>>10094061
They just leave out the trig stuff.

>>10094122
Don't see why anyone would bother learning that stuff? Just take a babby's first groups rings fields and everything in "college algebra" is just a simple corollary.

High school mathematics for University students call college algebra.

>>10094150
>abstract algebra
AAAAAHAAHAHAHAHAHAHAHAHAHAHAHAA

Wtf? In my University "Algebra 2" means Galois theory and many more things, not fucking high school maths

>>10093989
B&r

>>10093970
If you want to study algebra seriously, then you might as well start with George Chrystal algebra. Just download it from libgen.

How the hell do you guys still have a space program in America?

>>10097245
because instead of giving up on people when they fail the first time we work with them to help them achieve their full potential...

Not really, schools do it to drag out the math sequence so kids don't finish in the 9th or 10th grade and ask for advanced subjects. Publishers use it to sell the same book to multiple classes. See the table of contents of James Stewart's "College Algebra", "Trigonometry", "Algebra and Trigonometry", and "Precalculus: Mathematics for Calculus" book.

There is a large dichotomy in American schools. Plenty of bright students who come into college with elementary Calc, ODE, Lin alg, and jump right into the proof course, but there is an even larger chunk who are stupid.

>>10093970
not with that sheboon on the title

>>10093970
use khan academy idiot

>>10097766
Checked. Was immediately put off by the nigger pandering right on the cover.

>>10093970
You have the wrong book. Algebra 2 is a middle school class, you want a book on Linear Algebra.

>>10097800
I'm so confused on what's what at this point. Where I live the high school math goes from algebra 1, geometry, algebra 2, then precalc or stats. Is linear algebra within precalc or algebra 2? Or is it just it's own thing.

>>10097937
>algebra 1
y=mx+b linear equations, system of equations
>geometry
pointless
>algebra 2
review of algeba 1, quadratics, conics, methods for solving generic polynomials, some pleb tier matrix algebra, complex numbers
>precalc
review of quadratics/polynomials, review of complex numbers, trig functions, exponentials and logarithms, graphing

>>10097937
Oh I thought you were in college. If you're in high school then algebra 2 sounds about right if you're in your first year, I guess. But if that's the case you're probably violating 4chan's rules by being here.

In case you are in college and I just misread your post, Linear Algebra isn't part of either of those. It's mostly about vectors, space curves, and functions in R_n in general.

>>10098108
>geometry
>pointless
it's intro to proofs motherfucker
i definitely never would have cared for math if I hadn't known that my middle school geometry class was the most accurate representative
calc was fucking boring

>>10098246
>it's intro to proofs motherfucker

Done poorly. It would be better if they did a modern discrete math style course instead.

>>10098332
In 7th fucking grade?
Maybe in high school, yeah. But I think almost everyone is too far gone at that point to get good at being not an idiot. Ive been saying for years they need an AP discrete math as an alternative/extra to Calc BC.

>>10098352
Discrete math is 5th grade level

>>10098355
Have you seen the average comp sci major attempt discrete math? They're at an 8th grade level at least.

>>10098363
>Have you seen the average comp sci major

Yes, they have severe mental retardation. What about them?

>>10094061
At my high school precalc was just algebra 2 at double speed, I always thought the idea was that you learn the basics in algebra 2 and then master them in precalc

>>10098369
As somebody who's good at math and starting a CS degree next fall, I really fucking hope this is a falseflag.

>>10098714

>>10098715
So what would be the best route for somebody intelligent who is actually interested in the subject of Computer Science? Also, if any idiot can get a CS degree, then why do CS careers pay so well?

Discrete topics are not 5th grade. Lovász is unironically one of my favorite authors (one of his students taught me). I’m a mathematical analysisfag at heart, but combinatorics and discrete mathematics is legitimately such a fascinating subject.

As far as the difficulty of an intro to discrete math class? Hm, depends on your department. Here our most famous researchers are in discrete mathematics, so they go really ham.

>>10098736
I double majored in CS and math at a non meme school. Our discrete math, theoretical CS, systems design, and engineering are really strong, but your mileage may vary. I had a good experience and whenever I thought the course loaded was too light, they let me take a harder class in its place (usually grad level)

>side effects of pure mathematics
Five years back, before starting to study mathematics, I had read few books on CS related stuff. I remember in particular reading with interest and excitement that fat piece on C++, 9 years ago. Now such a book just gives me the creeps. I don't think I would ever be able to pick up any CS(or engineering or 'science') stuff, they are so tedious that my brain begins to bleed on its own. Almost any book or article seems to be unnecessarily long and very lacking that there is no pleasure in reading them. It would be worse than cleaning the sewers, and now there is no turning back. I feel incapacitated to do those things, but fortunately math and arts are still there, keeping me warm.

>>10099256
CS is a meme at every american school. Either go to Europe or self study it.

>>10093970
i remember that book

>>10099833
I did talks and taught a class at a European school. The only big difference is that they do analysis, which I’m happy with. I don’t like how in the US, they set most students up for just basic software development, but in Europe, it seems to me the students are of a lower quality. The program isn’t half bad. I just get annoyed when half don’t come to lecture
