since buying a book from somewhere means manufacturing costs + book license fees + some more cost to make profit I assume
Proof by assumption 
kkk. will check some stores near buy. Thanks! 
np
Does anyone know this book by callahan?
advanced calculus a geometric view
unfortunately I hated that book
oh
now is it visible?
ye
I'm gonna chime in here and say
The best Complex Analysis book is Marshall's
Stein and Shakarchi is really great, except for chapter 2 with the toy contours
I refer to S&S for their great exercises and problems
But the exposition is sometimes lacking
Ahlfors is also really great, but it starts off with a lot of geometry
Rudin's Real & Complex is amazing, but it's Rudin
So hard to read
Late response but you can probably find a printing service that can print it with cover for you at a nominal price.
Kkk
If you're still tied then you should look for books on discrete math or introduction to proofs that fit your budget.
(I have no clue about costs because I almost exclusively get them printed)
say, how do you go abt doing this? like, do you own a printer or something? or is there a place you can go to print it? and what do you do with the loose papers after?
oops sorry for the ping
.>
i forgot to turn it off
No worries
There exist printing services that allow you to upload PDFs, customise printing options (quality/size of paper, book cover) and get them delivered
i've always wondered how this is a thing cus does it not violate any copyright laws?

it doesnt
at least not in the EU
if you legally own a pdf (or book) you can make as many copies for private use as you want
right
Over here copyrights are good as non-existent for personal use in practice at least, even if not in principle
At least the printing services can dodge the bullet on grounds of "we don't monitor the contents of what we print to respect privacy" or something along those lines
oh yeah, the printing services might break the law 🤔
they certainly cant keep the pdf
Any calculus book recommendations
spivak's calc, apostol's calc, lang's calc
are all recommendations i've seen
stewart is also good for exercises 👍
well
stewart is the only one i have personal experience with
lots of exercises
probably good as a supplementary material
i've also heard spivak's probably isn't the best for an intro to calc
so i would recommend apostol or lang more
a calculus book that doesn't go over derivatives isn't worth glancing at
I wouldn't touch it
Apostol is just Spivak but written a bit worse, organized funny, and old school
If you aren't on a time crunch and you want to do proofs Spivak is perfect for a first course tbh
really? someone told me spivak was just not good as an intro
what kind of calculus book doesnt do derivatives
probably a really shit one
i would like to see one such book tbh
i bet i could make one 😎
smth like teaching integrals then saying "the concept of derivatives follows trivially from integration, left to reader as exercise"
the concept of integration follows trivially from derivatives ofc
Valley: it's harder than most
And it's only of much appeal if you want a fairly theoretical treatment
would you say it's a good choice for someone who wants to shore up their calc foundations and learn multivar?
im planning on using spivak to relearn calculus 3 after i finish linalg, just to get a better idea of it aside from R3
Hmm, based on how you're talking valley it feels like you'll want something more condensed, given that you already know computational single variable calculus
Have you done linear algebra yet?
nope, but i plan to self-study it with strang's linear algebra and its applications
although i'm also told ladr and ladw are good choices
so i'm having a bit of choice paralysis
ive heard ladr is flawed
also i wasn't sure whether multivar before linalg was better or the other way around
how so?
gonna be honest, not sure
but ive heard people suggest ladw over ladr
aha
idk much abt it but seems pretty convincing
i'm using H+K rn
Hello. I'm a half computer science student (rather not explain right now) and I want to strengthen my mathematical foundations/fundamentals. I have had a course on discrete mathematics as well as kind of "introduction to mathematics for CS" modules, but these introduction modules basically only touched on a number of topics. Moreover, my knowledge of calculus from school is basic and pretty 'rote', application of rules, etc. without a solid understanding as to the why.
So now I basically would like to ask whether I should start with 'mastering' linear algebra or calculus first?
(or something else)
and given the channel, suggest a textbook on said topic 🙂
under what topic do we read about double summations and stuff, and can some recommend a book for it
@brittle latch ask here, you were interrupting an active convo
Real analysis. I recommend seeing the last section of chapter 2 of abbot understanding analysis.
Really?

Anyone got a book recommendation for analysis? Going to be taking it next semester and would like to get ahead—would like to build some intuition beforehand
The usual recommendations I’ve seen are Rudin and Apostol; both are decent, although Rudin is more terse
Again, my goal is to develop intuition, not rigourously prove concepts. Would those two still be your recommendations?
watch some videos not read some books
What videos?
any recommendations for Measure theoretic probability preferable with exercises and solutions.
it should have a brief introduction to measure theory (Measures, measurable functions, fubini, radon-nikodym etc.) and then use it for probability
Why?
This established reference work continues to lead its readers to some of the hottest topics of contemporary mathematical research. The previous edition already introduced and explained the ideas of th
Why is it better
this book is very new but the content is very fitting are there perhaps older ones, with similar content
which 3 germans books, i am from germany so there is a high chance my university has them
yeah but i cant get my hands on them very easily and for free
thank you very much
has anybody had experience with either rotman's algebraic topology or advanced modern algebra
Book.
found a great book in real analysis
it even has full solution manual availabe
the downside is it is hard as f**k
and expensive as fuck
tbh using l/i/b/g/e/n is one way
yeah but the issue is that i prefer physical books :/
just go to print store
oh i prefer physical books too
but damn college loan
do you happen to live in the US?
What are some good resources for getting an intuition for the definitions in topology?
visualize everything in R^2

things like bases generalize how open balls generate e.g. the euclidean topology or that of a given metric space, the definitions of things like closure and compactness generalize properties in R^n etc.
always think of examples
When in doubt, think geometrically
What about the definition of a topology?
I can’t see how it captures the notion of “closeness”
just like in a metric space, two points are close if both of them are in "many" open sets
In what sense
Closure of a set kind of does
$x\in \overline{A}\iff $ for any neighbourhood $U$ of $x$ we have $U\cap A\neq \emptyset$
So x is "close" to A
If you expand it even a little, it crosses A
Uhh I can't unravel this, wut
its incomplete
Blitz
Here
This is not completely obvious at first sight if you defined the closure of A to be intersection of all closed sets containing A
So an exercise
Other than this there's not much surprises in early general topology course imo
It's all set algebra
@rugged seal Try Klenke's Probability Theory book
@gray gazelle Try Abbott's book and https://mtaylor.web.unc.edu/wp-content/uploads/sites/16915/2018/04/anal1v.pdf Taylor is notorious for terse writing, but this book is readable.
Book suggestions to learn all functions types, limits, derivatives and integrals?
Hmm, do you want to learn it rigorous?
If yes we have spivak calculus if not, any calculus book will do.
Stewart calculus is a common recommendation. Paul's online math notes work as well.
U can study with these books without teacher?
Definitely.
How?
Read, do problems then repeat. Ask questions.
I feel you, my favorite recommendation for learning calculus is paul's online math notes.
Here is a set of notes used by Paul Dawkins to teach his Calculus I course at Lamar University. Included are detailed discussions of Limits (Properties, Computing, One-sided, Limits at Infinity, Continuity), Derivatives (Basic Formulas, Product/Quotient/Chain Rules L'Hospitals Rule, Increasing/Decreasing/Concave Up/Concave Down, Related Rates, ...
Alright ill check that out thx
It's easier to self study using that.
Can I do calculus 1 without having seen logarithms?
And trig?
As in Pauls review is good enough?
Or do I need more in depth
logs and trig are fairly important for calculus
So I should spent a lot more time than just a couple exercises on a review?
You need to have a good understanding of trig.
log too.
Try khan academy for those.
Alright ill get started on that
How long would it take to finish that
And calculus I
Calculus 1 is usually a semester course. As I said, I can't tell you how long it would take.
Just get started and go through it slowly.
Sooner or later you will finish it.
Paul's online math notes has a college algebra course that has a section that covers logs.
Also paul's online math notes has a review for logs and trig in the calculus 1 course.
So you should be fine.
honestly, even this might be good but make sure you really understand logarithms and trig
logarithms and trig aren't exactly rocket science, there isn't a ton to know about them within the context of a freshman college course
you may want to review them on the fly while studying calc
trig is important for trig substitution on integrals, which sometimes is part of Calc 2
Are "algebra" and "analysis" separate things at the undergraduate level? Can I learn the em stein series1-4 if I only know "linear algebra done right"
algebra usually refers to abstract algebra at undergrad level, think rings, fields, galois theory, etc, while analysis is like real and complex analysis
i don't know the answer to your second question, sry
there's a good amount of overlap tho
Good books/courses for learning MATLAB?
No selfroles matching deying.
See ,selfroles --list for the list of valid selfroles.
thank you it looks great aswell
is there any book for linear algebra that is mostly theory rather than computational
That's algebra, abs is asking linear algebra
That’s not la
Linear Algebra by Friedberg, Insel, Spence
To elaborate: I think the book is the most clean and modern presentation of the subject at the introductory but fully rigorous level.
It does not try to be too complete
Not sure what you mean by "enough", but F.I.S. (my abbreviation) is not like Jacobson at all
Jacobson seems more like a complete reference
Dami said for Jacobson (abstract algebra) you'd want some LA going in
I suppose it's helpful to get some familiarity, but technically not necessary. You could develop the theory of rings and modules first, before specializing to vector spaces
yeah but aren't modules generalizations of vector spaces? lol
You can say that, sure. But sometimes more general things are actually cleaner because fewer properties means fewer theorems
true, but from a learning point of view, I may not understand the motivation behind some choices
not sure if that's true or not here but sometimes that's happened when I learn the abstract thing before the specific thing
This is true. That being said I don't believe that a standard text on linear algebra really prepares you in any meaningful way for a broad study of algebra, unless you're only studying modules, or only studying matrix groups
Other than perhaps preparing you via mathematical maturity
It's true that the connections run deep (eg with representation theory) but an actual course in linear algebra is focused on very different things
what is a linear algebra course focused on?
At the level of a 1st course, I'd call it a study of the linear maps and matrices
In particular how to decompose them and characterize them
There are several key topics that don't figure very heavily into abstract algebra
One is eigenvalue problems
Another is matrix factorizations from the standpoint of inner product spaces (eg orthogonal decompositions)
These end up being more like geometric study of linear spaces
Rather than algebraic
Linear Algebra Book Review
Traditionally, people do a first LA course focusing on computation at the expense of theory, then a theoretical course assuming you know computations. This is mostly because of inertia + first course is service course. I'm targeting this list for math majors, so I ignore books like Strang, and I comment when "second courses" are actually viable first courses
I think it's best to work over general fields whenever possible in linear algebra, since there's cool content over eg finite fields, and it's good to know whether you need the ordering on R (say for inner products), char 0, the field structure, etc. That said, ymmv. All these books cover some content that necessitates restricting attention, but I comment when books make that assumption right away.
- Lang: First book is computational, second is theoretical (self-contained, but fewer computations). Organization feels screwy, and it's probably boring to read because Lang. Works over subfields of C
- Linear Algebra Done Right: Calls itself a second course (meaning theory at the expense of computations), but it's self-contained and has rather gentle prose. Works over R and C. Anti-determinant, which in previous editions led to stupid choices. 4th edition is much better (I'd still change some stuff, but it's no longer unhinged), and now it's one of the few books that does multilinear algebra properly rather than just doing the minimum needed to define determinants.
- Linear Algebra Done Wrong: Works over R and C, balances theory and computation (prefers to prove theorems using row-reduction). Mixed reviews: some say it's great, but there are complaints about treatment of diagonalization and undefined terms in problems
- Halmos: Goal is to present linear algebra as finite-dimensional functional analysis, so it prefers the coordinate-free approach. Works over general fields (though a large portion of the book is on inner products and analysis). More theory than computation. Old-school typesetting and notation/terminology
- Hoffman and Kunze: Does matrices first which is fair but awkward. Extremely detailed, slightly abstract/tricky at times but not unreasonably so. Assumes fields are subfields of C in examples/exercises unless otherwise noted. Contains both theory and computations
- Friedberg, Insel, and Spence: Basically a modern Hoffman-Kunze. Somewhat easier (at the expense of some topics that are honestly cool), better organized (should canonical forms have come before inner products? Jury's out). Assumes fields are char 0 in examples/exercises unless otherwise noted. Contains both theory and computations
- Charles Curtis: Feels like a shorter FIS. Friends who used the book in a course didn't like it, and at a glance its organization feels screwy. Balances theory and computations.
- Morton Curtis: Very abstract and efficient, finishes off by classifying normed algebras over R. Works over general fields, and uses multilinear algebra for determinants. Prioritizes theory, and in fact omits stuff like SVD which are imo important (though it's surprisingly complete for what it does cover, given the length)
- Shilov: People here seem to like it. Very hard hitter, works over a general field, and covers more advanced topics. Starting with determinants feels like a meme
There are books I'm less familiar with (never referenced, TAd from, or had friends comment on) which seem interesting. Katznelson-Katznelson looks quite efficient, though it does many details such as Vandermonde matrices and SVD that eg Morton Curtis misses. Greub feels like The Reference™️ and quite a hard hitter. Roman is on crack: does module theory and Hilbert space stuff, also "Umbral Calculus" (?)
Some algebra books, such as Knapp and Artin, develop linear algebra from the ground up. If you're clever and want to move fast, those are worth considering (Knapp seems harder than Artin).
This is my take @solemn mantle
Probably the correct answer tbh.
Based as fuck
Yeah I saw quantum complaining about LADW diagonalization yesterday
My only exposure to LADR and LADW was in choosing which book I wanted to teach from
I felt that both were extremely idiosyncratic, for no particular reason really

Given the future interest in learning algebra I agree Artin is a decent choice, though it's not a complete coverage of linear algebra
I was formerly teaching while I was a postdoc, no longer, at least for now. And yes my area is applied math
Is roman bad? Or is it significantly harder than the other texts
Roman is very niche. It's explicitly not a first book, but usually by the time you're ready for Roman you're reading algebra and functional analysis books rather than linear algebra 2
Good stuff Mipchunk
ah I see
Anyone here ever read Altman and kleimans commutative algebra book? If so what’s your opinion on it
Seems like a more modern Atiyah-Macdonald but somehow he exposits in a way that pisses me off and I'm not sure why
(Haven't read much of it tbf, just that what I've read turned me off for reasons I cannot put my finger on, so ymmv)
@sage python funny you say that, I was thinking the same thing reading the first few sections
I think for me it’s just too terse
Maybe that’s the wrong word, I guess barely any exposition in addition to the math itself
I've not, but I've heard it's really good, at least as far as rigorous calculus texts go
I personally feel that there's enough calculus resources online and floating around that the concept of using a specific book is not necessary
Mipchunk is this blasphemy against our lord and savior Spivak?
Spivak is goat
(To be fair I do think some things could probably be improved upon in Spivak I just find it funny to be like :0)
I used the Ron Larson books for ap calc
Lucy: honestly if you already know computational calc you can probably do an analysis book rather than Spivak

I found this one book lately by Browder which tbh might just be superior to Rudin
Jury's out
Is rudin generally more in-depth than spivak
More general
What's the full name of the book? Just curious. (im a billion light years away from analysis but just curious)
Like
Spivak does things in the "calculus way" rather than the "analysis way" so to speak
By the way thank you very much for this, shouldn’t you pin it?
For instance, his proof of intermediate and extreme value theorem avoids topology in favor of working directly with suprema
Ha. It's more that I object to the idea of tying studying math to studying specific books. Too much emphasis on trying to do things the "right" way
If you guys think it's good sure. Mipchunk any objections with that linear algebra review?
I don't have any skin in the game, it's up to you 🙂
Fair, I guess just since you taught linear algebra do you think it's a fair assessment 😛
I've only taught from FIS, Axler, and Lay
But also, teaching from is very different from learning from
When selecting a book to teach from, you pay attention to things like good exercises to steal HW out of, familiar notation, and good ordering of topics
But maybe less attention paid to exposition
allyc will be happy
u can kind of try to wing proofs
like doing basic ones ur self, and getting an idea of how they work
you haven't said anything about hubberd's
Hubbard and Hubbard?
ye
(i dont happen to know of any specific proof teaching series, but i think some youtubers like michael penn and prof leonard might have something for u)
I'll check it out
Hubbard feels a bit off to me for some reason
idk why

true
well u can ask for help here, to verify proofs and stuff
i dont think they are much cons
i really like apostols book
i havent completed it by far
but its got everything u would need
examples, proofs, theorems (these should be there, obviously)
and exercises, a ton of exercises
From the table of contents... I'll be honest this feels like a "the linear algebra you need to introduce to teach something resembling a correct multivariable calculus class without explicitly requiring students saw it before opening this book"
really nice ones as well
Defers a lot of proofs toward the end which is bizarre
Honestly this book is just incredibly strange
yeah exactly dami
I feel like Shifrin's probably just better tbh
Multivariable Mathematics by Ted Shifrin
It's this but with less of a wtf organization
only the particularly hard ones or the ones it deemed less important
not trying to say anything about apostol but these are just things present in most math books ?( I mean like undergrad books and above )
yeah as i said, these should be there in a good ug book

but its that apostols problems are pretty damn good
Yeah ofc not all the proofs are being deferred lol
like, the topology chapter has 50, limits and continuity has 70+
Just that like
Fwiw a large number of problems isn't a comment on their quality
Wait artin … I want to learn linear algebra and abstract algebra, is this both in one? I was going to try Jacobson later on at some point but now artin seems like a better choice. Is there any downside?
Idk it feels like it's trying to achieve some weird balance between being good for calc 3 students who care less about proofs and for honors math students that wanna do things right? That aside though... idk it mixes shit up in such a bizarre way
i said good problems bruh
I haven't read much of Artin myself tbf abs_0, but at a glance it seems good
Yeah idk how much I like it. I could see it appealing to a certain niche
In any event it doesn't include enough linear algebra to be a contender on this list
Artin is a great survey of algebra and is thus very suitable for learning, especially as a first time through
I like how LADR is the first one on the list lmao
I'm planning on doing artin later on, so maybe it'll be enough to fill the gaps
@sage python did you check Tao's linear algebra notes? It uses FIS as a supplement and is pretty short(almost 300pages)
Idk Tao's notes
My own path through linear algebra was basically
I did an REU summer after first year which had a class that was a week of graph theory, 3ish weeks of linear algebra, and a week of spectral graph theory
That’s awesome, wdym survey?
(It was 2 and a half hours/day, 5 days/week, so we did cover a fair bit)
Artin covers many topics, but not in too much detail
Wow that’s perfect
I had LADR on hand going in but honestly the lecturer was extremely good, and did things in a different way than LADR anyway, so I never really used it much
Surely you know that question can't really be answered!
Then I took an analysis class and... basically up until that year we didn't have a linear algebra class. You did a few weeks at the end of calculus, some stuff in analysis as needed, and mostly during the ring/module theory quarter of algebra
But then the department was like nah we need to have a straight up linear algebra class, and we'll make it a prereq for second quarter analysis (where they start multivariable differentiation)
Easy to unfathomably difficult
I don’t know rudin but if it’s proof based they will not be computational at all
Except honors analysis taught the multivariable calculus already during first quarter, and profs just taught the linear algebra they needed
Well the goal isn’t to do every single exercise
So the department said alright if you do first quarter honors analysis you're exempt from linear algebra
Corollary the prof now had to cover a full course in linear algebra along with the analysis. Which our prof didn't want to
So he just gave us the book that the linear algebra class was gonna use (Hoffman-Kunze), each week had us read the chapter and do an extra pset from it
578 votes and 71 comments so far on Reddit
Time estimates will be difficult because the problems vary so much in difficulty. There are probably some that could take over an hour if you get stuck
lmao
My friends who took linear algebra told me they used "Abstract Linear Algebra" by Morton Curtis instead since Hoffman-Kunze was out of print. Ended up being a bit much. Switched to a book written by a different Curtis which idk well. Eventually settled on LADW which seemed to be good from what I've heard/checked out. And I graded psets from a class using FIS
Plus I tried Artin a bit when I started learning algebra before I switched to D&F and eventually to Herstein
So that's pretty much where the list I'm reviewing comes from
This reminds me of spending one whole day on 3 basic set theory qns

@gray gazelle to understand set theory and logic I have a book I really like, it completely babies you but it’s perfectly rigorous and understandable
Those are the most fun ones
Oh nice ok you’re set with that
Wait do you already understand set theory and formal proof
Oh that’s rly cool
It’s fun yeah
The exercises are hilariously easy, but it gives you a very solid basic instinct about logic
u need some logic and idea about how things work for analysis yeah
No you definitely need all of it
It’s also fun because it makes it very easy
But yeah I recommend it
Rs Aggarwal grade 10 has tough math questions and if you want even though ones then try ML Aggarwal
Updated the review slightly to go into more detail on Morton Curtis
Also threw in a lol for Greub
Because lol
the people currently talking werent looking for 10th grade problems
lmao
can you do a few more of these book review thingies? for like say functional analysis, or diff geo
or comm alg
stuff like that


What's a good beginner book on ODE
i found book of proof by hammack to be better
same
just read boyce
tbh ode shoudn't be that hard on undergraduate level
if you didn't totally screw up your calculus course
are there any good books for referencing trig , exponential and equations
I threw away my high school and middle school textbooks
and am regretting it
Don’t regret it, those books were probably garbage in comparison to what you’ll find in pins
Honestly wikipedia is a good reference for those things
I constantly hop on to wiki to find the identities I need
I tried linear algebra done wrong and I found that to be a little difficult, not because of proofs but my lack of knowledge in linear algebra, such as matrix multiplication, etc. could anyone recommend a book that if rigorous but also introduced those topics?
I don't suggest trying an "all-in-one" approach for this. There are lots of free materials online on just the calculation elements of linear algebra that can supplement a more rigorous book.
There isn't any, Boyce & DiPrima is alright. Better if you can get an older edition (before 5th?)
Schaum's outline to ODEs is decent too
but I wouldn't call it "good" by any stretch
what online recourse would you recommend then?
MITs OCW for linear algebra is decent, I used that course many years ago. I think some people use Khan academy as a simple intro as well.
Whats the best textbook for commutative algebra......?
bible?
eisenbud
good, matsamurua or atiyah macdonald
@gray gazelle is good a name
i like your name also

I mean is good a name
@gray gazelle
Differential Geometry Books & PreReqs?
?
.
Have you already studied the basic concepts, e.g. basics of topology, smooth manifolds?
Lee's "Introduction to Smooth Manifolds" gives a decent survey of some of the main topics concerning smooth manifolds and a few topics in geometry
For strictly differential geometry, there's Do Carmo's "Differential Geometry of Curves and Surfaces" as well as his other book "Riemannian Geometry"
You should know vector calculus and linear algebra at the very least. Real analysis is also valuable.
You can try A Course in Game Theory by Rubinstein and Osborne, Game Theory by Gibbons. Even Microeconomic Theory by Mas-acólelo and Advanced Microeconomic Theory by Jehle & Reny have some chapters devoted to game theory
Oh ok thanks
Schaum's outline to ODEs is great because it solves a million problems
which is honestly what you need in ODE
Don't forget to brush up on Calc 2
Ok thanks so much
yUh no problem
And for PDE what would you recommend I use?
Ok
So have you learned real & complex analysis?
That'd be like Fourier (S&S volume 1), Rudin chapters 1-8, Spivak Calculus on Manifolds, and pick your favorite complex text
If you've learned that stuff I'd go for Evans PDEs
If you're still in undergrad material pre-analysis Walter Strauss' book is alright
But honestly going into Stein and Shakarchi's Fourier, then complex would probably be the best
Since to do PDEs "right" you need a lot of real/complex analysis, and ODEs
And several variable calculus a la spivak calc on manifolds
@gray gazelle Hope this helps, but if I had to pick an order, it'd probably be like S&S Fourier, then Rudin, then Spivak, and you can do complex at the same time if you feel you have time
Ah ok
Rudin's "Principles of mathematical analysis"?
Yeah, baby Rudin chapters 1-8. If you intend to go further in PDEs
You need to know real & complex pretty well, like the back of your hand
(Even functional, but I haven't learned functional so I can't gripe)
Does complex appear a ton in PDE?
If you go a harmonic flavor it does
But also thinking about things geometrically
Yeah
Iirc dispersive PDE is fairly big on the harmonic analysis
Elliptic PDE with calc of variations?
Elliptic PDE you wanna know your complex for sure
Maximum principle
etc.
A lot of complex is PDE theory in disguise
Geometryhards will try and tell you otherwise
I do agree but I thought it was gonna be the opposite flow then
Like oh it's good to have some idea how elliptic PDE work before complex since you'll mirror properties of harmonic functions 😛
Honestly Souganidis prob just believes that
In other news I got my teaching schedule for next year??
Mooney told me that Elliptic PDEs takes 2 years to go from beginner to research
If you've done the analysis thingies
Ofcourse time may vary by maturity level
Yeah I think Soug doesn't give a shit about complex analysis is the thing haha
I can see this: from a current perspective, a lot of it is dated and not useful
If you wanna do relevant research
Complex will hardly show up, but you know what I had to do in my fucking research on day 1
Multivariate taylor series expansion and integrating factors
So when I teach calc 3, everyone's gonna learn about multivariable taylor series
Yeah, but one of the most employable fields in math
One variable is enough
Don't like academia? Bee-line for industry right there
Do like academia? half your competition went to industry for better salary
If I could do anything I'd probably choose topology
Just gaslight industry into thinking that multiple variables is just one variable
But y'know a man's gotta wife and what not
I'm teaching trig next year
Should I just teach fourier instead
Gross
I got 2 pre-calcs, some algebra, pre-algebra, geometry, & trig
(Classes meet once per week)
With trig at the end of it all just use complex exponentials anyway
I taught inverse trig derivatives last week
Using inverse function theorem
In the pre-calc class, even tho it wasn't in the curriculum
That feels a bit odd lol
And my company has the audacity to try & say Stewart will be the calc book for our curriculum
Spivak bruh
They don't even cover the inverse function theorem!
Honestly, I might just bring my copy of spivak and say
Do this instead
I don't think there's a canonical one here, just do as many problems as you can
If you get stuck for longer than 15 minutes, look at a solution
Khan Academy is good for most things iirc
Then write down what your mistake was and reflect why you made that mistake
Try to find something every week or 3 weeks to "test" yourself honestly
Be as mean as you can to yourself
When you grade, don't give any pity or "Oh I almost got it"
None of that
I've heard that Spivak's Calculus isn't for beginners
Ok that's wrong
It literally starts with 1 + 1
Spivak Calculus starts from scratch, it's a difficult book but it's not undoable
You have to be dedicated to make it work if it's your first frolick in calculus
I went into it barely knowing any calculus (I placed out of one quarter of calc in college, so not even the integration class), and the only proof I knew of was induction
hmmm
And I found it quite doable
what about Stewart's?
Stewart and Spivak have different use cases
I went into it with failing most of HS math, and it was a combined class (calc 1 & 2) so we did derivatives and integrals at the same time
And I came out of the spivak class just fine
A lot of non-mathematicians need to know calculus
e.g. natural science, engineering, economics
oh well, you guys didn't self teach
Stewart is like the McDonald's of Calculus, it'll get the job done ~ just without any nutrients
Those guys don't really need to think very hard about how you prove the intermediate value theorem using suprema
Like
Just know how to use what comes in your stuff
hmmm
Thomas' University Calculus is a superior text to Stewart's in many ways
Stewart has a bit of delta epsilon proofs and all floating around but its emphasis is on not shoving unnecessary stuff in the face of people who don't need it
Many of stewart's "proofs" are infinitesimal hand-wavy arguments
Also in the multivariate section, Stewart just straight up doesn't give enough examples
Spaced repetition. Put something down for a week or two, go do something else
Within its category I'll say that there are probably options that are approximately as good but much cheaper
Come back to it every now and then
Probably Thomas as Moonbears mentions
Spivak is more meant for students who are actually gonna be math majors
I straight up wouldn't use Stewart for Multivariable
So the theoretical development is important
Noneuclidean when there are a lot of duplicates once it's super clear you get the point move on
Wait a few weeks, do some more problems you haven't done
The worst thing you can do is open up 1 chapter, and try every problem
In one week
You want longer term memory
But yeah that's the whole Spivak vs Stewart thing imo
If you're self studying and not on too much of a clock
so, having some knowledge of proof writing before taking Spivak's would help
There are other issues I have with Stewart's calculus text (Lack of Inverse Function theorem, atrocious proof of quotient rule, lack of good examples, too many exercises require a calculator, etc.)
I mean like I said I knew how to prove that 1+...+n = n(n+1)/2 and shit by induction
Spivak can simultaneously be an intro to proofs and an intro to calculus
hmmm
As long as you're not in a rush
It'd be hard to learn spivak on your own, usually you need a mentor that can guide you through the forest when you get stuck
It's not entirely trivial to pull this off, since calculus proofs have sneakier logic than discrete math proofs
I guess this discord can act as a proxy
But it's doable
I'd say it's only worth it if you really like Math for Math's sake
It might be easier to just do fast-food calc
and come back to rigor later
If it interests you
why is it sneakier? is it usually because it deals with uncountable infinity?
I mean, real numbers are uncountable but I don't think you're referencing that a ton
It's the nested quantifiers
so introductory discrete math courses use less FOL?
FOL?
first order logic? cuz most idscrete math usually sticks with propositional logic?
well that's what this server is for
You get a feel for what a solution should look like
Honestly I don't think too hard about what type of logic is what lol
I just mean like
how long do you think it'd be to study the entire book?
how long did it take you in college to learn it? @sage python
When people hear for all epsilon there's a delta such that blah blah
idk i think discrete math, most things are countable
while in analysis, its more open balls, and shrinking infinitely, in uncountable ways
They get confused
They're like oh wait for all delta there's an epsilon
Or like accidentlaly make the delta depend on both x and epsilon
etc etc
So I'm not sure about formally what's propositional or anything
never mind me
i personally feel proofs on Z are easier to visualise than R, and I was blaming that on it being countable or not
but i don't think thats the only reason why calculus proofs are sneakier
it might be a factor, who knows
it's probably best to do it right after each exercise since you'll remember what you did, so if there's anything wrong so you can trace back and find the mistake
this doesn't sound like it'd be useful at all
Apologies if I've missed any general pins that answer this question. Can anyone suggest some books that would be a great start for differential geometry?
or Lecture notes
You want to learn manifolds?
Pollack and Guillemin or Lee
Also there's Hirsch
I think people consider Milnor to be a cute introduction
You're so sexy man I appreciate you
Thanks 
Would Riemannian geometry be a good place to move onto after the Manifold stuff?
I'm just a tad confused on the progression of things
Yeah, I think so
No
I wonder what approach you take for more theory classes? Like in general how long should you attempt a proof before realizing your not making progress and look for the solution. That is a tricky thing for me when self studying and I can't check with other students in the class.
What book are you using
I think after what I went thru to learn basic concepts/proofs, the best route is probably Chartrand and Zhang
I need a book! I need a book to understand differential equations.... like "differential equations for dummies 101 basics for slow people" >__<
tag me or dm me >__< thanks
_<
Any mathematical reasoning/mathematical logic books \
teschl 
Is there a comprehensive book on formal logic that covers classical, intuitionistic, linear, modal, temporal and fuzzy logic?
need a book comprehensive on basic geometry that doesnt require anything more than algebra & has lots of problems
Good luck
You can try an introductory topology book but you probably still need to go through some kind of analysis based text at some point I would imagine, to get very far in something like algebraic geometry or differential geometry
no i dont mean anything advanced but like comprehensive on the basics with lots of problems
Oh
my bad i will rephrase the question
Topology isn't geometry
He edited his question though 
Maybe it was a good advice for the previous question, we'll never know
Nevermind
I believe they were asking for a euclidean geometry book
Stewart, early transcendentals
The geometry book by AOPS is my favorite for a first book. The geometry books by kiselev are also really good.
It’s not but it’s not totally unrelated either
Originally AFAIK topology was considered a subfield of geometry but too many debates happened I guess
I would say geometry really mostly is how we abstract spatial concepts in mathematics
So those concepts are not mutually exclusive to being geometry but part of other fields for instance that pertain to algebraic structures*
AoPS geometry for sure. Great explanations and over 900 problems with written solutions for everything. https://artofproblemsolving.com/store/book/intro-geometry
Why is topology not geometry? Topology feels like if you took geometry, forgot what measurements were, and made a whole field out of it
thats what it is
Topology studies limits and continuity. That's all.
For someone good at algebra 1, geometry, algebra 2 what books to master them?
You can try higher algebra by Hall and Knight
That’s good for practicing and learning algebra
1 or 2
Or both
Both
But better if ur 2
Oh no i just wanted to perfect it for SATs im in diff eq
Ok so u want a calculus book?
No I use spivaks
Ok
It’s great
You should try it
Ok, im doing Apostle rn
Apostol is really good
That’s pretty good too
Yeah
Ye
Anyways, if you want to master algebra, Hall and Knight’s Higher Algebra is my recommendation
Yep reading rn
After which I guess I’ll do AOPS geometry
Yeah that’s good
Can someone recommend books to learn basics of calculus, algebra, trigonometry etc?
.
What's a good college/university level book for starting with proofs? Should I begin with something geometry based, or go right into something specific to proofs?
if you want to learn actual mathematics, you should not read a highschool geometry "proof" book
Hard this. No one uses that style and it disgusts me that they're taught that way
overall i dont think an intro proof books is that useful, for a short introduction you can check my text pinned in #proofs-and-logic
if you want a longer book, people like velleman (which i dislike) or hammack (which i dont know), alternatively i like aluffis notes http://www.math.hawaii.edu/~pavel/Aluffi_notes.pdf
I don't understand, and bare in mind I'm coming into this as an outsider.
What about studying Euclid's Elements itself? I realize many of the proofs and assumptions have been questioned over the years, but his approach is proof + geometry based. Is this not the basis for proofs in modern mathematics?
Hmm. Well, of course I want to optimize my study time with the most relevant books possible... Let me see if I can find your note. @stray veldt
The link to the msg if you cant find it ^
more precisely: euclid did what is known as synthetic geometry, which doesnt have a very big place in modern mathematics
similar style of math was employed in the 19th century and is still done today to some extent, but its not a big theme in modern mathematics
besides, euclidean geometry itself is 'solved' and not studied anymore
the big appeal in the past was deriving theorems only from axioms, but today that is just all of math and other math is just "better"
Got it. Interesting intro, thanks for writing this @stray veldt .
What do you guys think of books like An Introduction to Abstract Mathematics by Bond or Mathematical Proofs A Transition to Advanced Mathematics by Chartrand, Polimeni & Zhang? I'd like to develop my ability to do and evaluate proofs
I should mention I'm not necessarily looking for research topics right now, just skill building 🙂
I've loved book of proof by hammack
it has a lot of solutions and its free
tbh you can just pick any of the book and it will be fine
though it might be good idea to read amazon or maa reviews first
Can I recommend non math books?
yes at least to me
Really high reviews on Book of Proof. It looks like it's more revolving around Discrete math?
hmm
more like mixture of discrete+set theory+logic
teaching you essentials of proofs basically
Ah nice. I shall check it out then.
Ye apostol sorry
Yeah, it is mostly discrete math. Most of the examples the book uses come from elementary number theory, I guess presumably because that requires next to no prerequisites beyond high school math. There is a dedicated calculus chapter, but the rest of the book doesn't assume any prior knowledge to my understanding. I too would recommend Hammack. Really well-written and understandable.
If you think about it too, geometers also deal with lots of limits and continuity don’t they? Haha
I like to think they are different lenses of approach to certain concepts
Hello, everyone! I’m working on my own through the beginning of Friedberg to give myself a chance at a full run-through of linear algebra. I have familiarity in abstract math, but much of it came from cherry picking topics or learning with an application in mind.
With that said, Friedberg seems just a touch slow to me, and the exercises a hair easy (not all, but again, most)
Would Artin instead be a good alternative, or am I just too early in the book? (Only Chapter 1 finished so far)
this list was made recently and artin seems to fit your bill @night prism
Thank you!
i see my diagonalization comment was acknowledged 
Too early in the book imo. Artin is a broader survey of abstract algebra and it also doesn't cover linear algebra in as much detail
At chapter 1 you've basically just defined vector spaces.
Friedberg is just a more complete book (on linear algebra specifically), even if perhaps the first chapter is too slow
Ok, understood; would Morton/Curtis be a good book to concurrently read for added perspective and approaches to overlapping topics, or better relegated as a second treatment after finishing Friedberg? Thanks so much for everyone’s insights!
I don't know the book unfortunately. By the way I think that Artin is a great book and develops a lot of the foundational concepts of algebra quite well. As such it has a largely algebraic slant, whereas I think to fully be an expert on linear algebra one should also have a geometric perspective (esp since a lot of "useful" linear algebra is done over R and C). For example I do not remember Artin covering SVD or really saying that much about eigenvalue problems at all other than the basic definitions.
need a friendly trigonometry book
Ok i understand, will stick with Friedberg then and maybe browse through interesting sections of Artin. Thanks much for your help
hey guys, I want to start studying Group Theory for hobby because I think it seems pretty interesting and fun. Any books you recommend? Bare in mind that I'm a sophomore CS student, so my mathematics isn't that advanced (but I'm able to read somewhat complex math texts because I've been doing a research on discrete dynamics) and I'd prefer a more introductory language.
visual group theory?
Abstract Algebra with Applications by Audrey Terras
Group Theory but I guess the right term is abstract algebra
oh I mean that's my recommendation
oh
the book "visual group theory"
ok I'll take a look at those two!
do you guys think there are any prerequisites before I get started with group theory?
have you seen proofs before?
Terras? I think Pinter has been fine so far and im working through that currently
then you're good to go
I recently found this book and it introduces abstract algebra with applications so I think that's pretty cool
Yea I’m actually noticing my improvements in maths
I am going thru Knuth and Matousek to approach Bona’s combo + graph theory book
Yea Pinter is a fun one and there’s some fun problem sets in there that aren’t overwhelming
I guess I'll take a look into Relations a bit better because I feel like I'm a bit weaker on that end
set theory I could say I've learned so well I don't even wanna talk about it anymore
Relations is where you start learning about functions
It’s the other half of math other than algebras
alright, guess I'll revisit functions and relations then before getting into abstract algebra
cuz I really suck at it
Well actually go thru Pinter and Chartrand and Zhang? Try that route
The chartrand and zhangs abstract math transition text
Shouldn’t take you long
You basically can go thru the relations part. Then you may be ok to go thru a book like Abott’s understanding analysis for more abstraction
If your already good with the rest of basic concepts
"A Book of Abstract Algebra" this one?
Yea
So functions are just about assigning some relational meaning between sets, usually it’s some computation involving fields in R or C
sometimes I just get the concepts of things like bijections confused
Injection means you have elements uniquely map from one set to another
Surjection is you have all the elements of one set map to another set (maybe not all the elements of another set though)
Bijection is both
so like
hm
yeah alright
I think I got it
I'll do some exercises to review though
I think injection is the hardest for me to understand
injection is like, every element is mapped uniquely to another element
right?
Hi I wanted to recommend this book to anyone that is in last years of highschool and knows some italian
It is the "plus" edition so it has some additional things about integration, derivatives and probability density.
However, if you don't want the "Plus" version the standard one is quite good as well
Note: this book is in Italian Language
It's called "La Matematica A Colori 5 PLUS"
I was checking out reviews of Artin’s algebra text and some were saying it’s written very concisely and is not good for self-study. Is this true?
it isnt objectively true. Plenty of people really like the book. Try reading it yourself and seeing if you like it or not.
Ok thanks
I'm asking for a book a becouse last one didn't include all topics
I'm looking for a integral book that contains.
1/integration using trig identities
2/partial fractions
3/same standard int formula based
4/definite integrals using properties
5/integration by parts
I'm currently in grade 12 India
||my current book i.e (RS Aggrawal) has missing pages from integration chapter)||
Stewart's Calculus has all that
any engineering calc textbook should, really
I own a calc book by Dennis Zill (found it cheap when I was a freshman) which also has all that
and by "engineering calc" I mean any textbook that focuses on calculations, visual intuition and applications rather than proofs
Thomas' Calculus or it's variant: Thomas' Calculus in Si Units by George Thomas
if you do find artin too difficult for self study you can try pinter's abstract algebra book, which is much easier but still rigorous
I don't have an opinion either way for Artin, but a book could be not suitable for self-study without being difficult. It could simply not be thorough or detailed enough, or have extensive enough exercises to give the reader good practice.
Ah good point
I just read the preface of Pinter and wow I really love that
Seems like he put a lot of effort into good pedagogy
Good book for abstract algebra?
First course or graduate level?
Check pinned messages for my review of algebra books. In a nutshell, Artin's the correct answer for absolute beginner (as in, you don't even really know linear algebra well). Jacobson is my favorite, D&F is a more standard, drawn out, imo less interesting alternative. Lang if you're a masochist
I know linear algebra but otherwise first course
By jacoboson u meant basic algebra 1 right?
Yea
is Higher Algebra a good book for national olympiads?
higher algebra by lurie? no
an extremely intimidating looking book
Which author(s)?
I'm aware of a book by Hall and Knight, and it may or may not be very helpful other than the bare minimum I guess.
The other one is by Lurie as pointed out and I'm not aware of any research mathematician tier olympiad where it would be useful. 
When I had to learn select topics in algebra, Fraleigh never made me feel left behind. @sage python advice is probably more sound, however.
what's a good book for general banach space analysis
I've tried Yoshida once and it was pretty good tbh. But I haven't read a lot
But not sure if it's what you're looking for
try pederson's analysis now ch2
pretty good imo
The Subtle Art of Not Giving a F*ck is a good book
Bruh
wdym “bruh”
I read tht
isnt it good
ImoPov no!
It's the first book I've ever read
Try sapiens in case u didn't
It's great
Ofc
added to my list
Symbolic Integration by Bronstein
Yes, it's about algorithms for calculating indefinite integrals
oh that sounds cool actually
Can recommend anything regarding pshyc..
Taylor Classical Mechanics
Bruh I said phsyc
psych?
Yeah!
the deepest well
It is, but it's more for a computer tbh
it’s about the connections between mental health (esp. trauma) and physical health complications
A lot of cool algebra there though
Any other?
the empire of depression
Sounds cool
How abt behave??
behavioral psych?
So called differential field theory
never read a book called behave
Thinking fast n slow??
I only read math books, sadly can't recommend anything
Oh thts fine
Are u in uni??
Yes
Masters ig
Doesn't matter
I'm not into set theory but I did consider learning it more as it's useful for deeper understanding of some things in topology
So called set theoretical topology
Woah great
I did a course from game theory but I don't remember much
But I recently learned about von Neumanns minimax theorem which has some cool applications I guess
I think it's a jargon
😅.
Huh
It's a theorem in functional analysis that has applications to Nash equilibria
Yeah
I heard tht too
I think I got tht from scishow
Hank
Do u watch those hank chnls??
But there's also an application to fixed point theorem for affine maps
So called Markov-Kakutani fixed point theorem
It's a perfect tie situation where it's the perfect situation for everyone
Am I right?
*nash equilibria
I wouldn't say that tbh
U r throwing sharp jargons at me😔.
But I'm not advanced in game theory at all
It's my rough estimate 😅.
You can prove that under some assumptions they have a common fixed point
Probably I want to do math in uni
I think it's nice but I haven't seen it applied yet
Thank you? Lol
is precalculus just algebra +trigonometry?
Yeah
guys
I need a good book to get good at linear systems and matrices
currently using College Algebra by stewart but idk I think I could use something more advanced
does anyone have any recommendations for good measure theory books? Not looking for learning content, just challenging but not impossible exercises
found a good book on multivariable analysis
this even has solutions
isn't munkres also good?
i've heard that munkres was good too
tho i haven't used it
we use rudin for our college and I detest it so much
hmmm
do you guys like studying with solutions?
had a look at this and it looks perfect, thanks
yes
i like it bc i know when im doing stuff right, but i also feel like i learn better when i dont have them
bc
if there aren't solutions, i'm more motivated
to actually
solve the problem
instead of giving up after 10 minutes
yeah it's a balancing act
I do feel like peeking at solutions can still enable learning
as long as you pick up the idea and flesh out the details yourself rather than just copying the solution without thinking
to be honest i don't really look at solutions
before 3 failed attempts at solving a problem
even then I try to look only parts of it
maybe cuz im stubborn
tbqh right now I do look at solutions more often than I should
more because I'm revising for exams
so I'm more concerned about being able to answer exam qs than learning the maths xd I'll try to catch up on being actually good in the summer
I do most things on my computer, I only handwrite to practice for handwriting in the exam
maybe thats of preference
but looking at solution manual isn't really a recommended thing tbh
unless you have exam tomorrow
and you haven't studied
online book club?
seems interesting
on my list I have distributions, fourier analysis and more functional analysis
i also want to learn basic algebra like galois theory kind of stuff
even though i prefer analysis
but that's for the summer after i've done celebrating end of exams
I have manifold theory and complex analysis
maybe a bit of algebraic topology if possible
im thinking of going through real analysis, abstract algebra and point set topology over the summer
oh im doing both this year and both have the potential to be quite nasty exams for me
my goal is to at least understand proof of stokes theorm on all manifolds
ive done not enough pdes
oh thats actually not too bad
you mean manifold and complex?
yeah
which book do you use for complex?
you mean pde using analytic methods?
doing that + 2x functional analysis, probability, pdes, measure and set theory
well i've mainly done my lecturer's exercises but I think I'm going to pick Ahlfors and Ablowitz and Fokas
is ablowitz and fokas rigorous?
i'm not sure I haven't looked at it for a while, I learnt complex for a while prior to taking the course formally but the lecturer puts more of a geometric spin on it all, so I don't think something applied-ish will be too bad
also he's not very tight on a lot of details
idk I like all those courses but PDEs was my least favourite
even though I should like it - it was just a bit dry playing around with integrals
the coolest thing was finding out that harmonic functions are to real analysis as holomorphic functions are to complex and they're extremely similar
dunno about graduate pdes
that's about it xd
sounds like a lot
Are you talking to me
yes
i did linear algebra last year but not a lot of it was relevant to what I want to do
I'm gonna do tao's course
theoretical one
the linear algebra you need for analysis is pretty basic
whats CLRS and FIS?
or ones focuse on matrix?
the one i did in first/second year was basically just finite-dimensional stuff with matrices ye
so not very relevant to me
oh
lol
thought it was abbreviation for some computer related stuff
my bad
mine is tu's introduction to manifolds and conway's complex analysis
anyone?
can you specify
if you only need to know how to calculate matrices strang's linear algebra should be fine
I'm gonna take linear algebra next trimester but I don't wanna get stuck with the linear systems and matrices stuff, I know linear algebra is made specifically to solve those but I wanna get a head start you know
strang's linear algebra or lang's linear algebra introduction is what you might be looking for
I don't recommend anton's book btw
apostol?
ok i'll take a look
haven't read apostol linear algebra tho
my school recommends apostol
but idk
I read a few pages of it and it seems confusing to me
apostol isn't the most friendly author btw
alright
thanks for the help man
btw is this the one from strang? Introduction to Linear Algebra, 3rd Edition
Textbook by Gilbert Strang
yes
what are the prerequisites for chaos theory and dynamics in general? and what are the sorta standard books for both
for dynamics, i know you need a ton of diff eqs

idk anything more than this, sorry
Pretty sure strogatz is the standard undergraduate textbook
can anyone recommend an introductory book about bio-informatics (or anything biology-related from a mathematical point of view)
any book recommendations to enhance math writings and to get better at putting thoughts into words
I don't know if any book is dedicated to that, but there are a number of notes that people have written about how to write mathematics
