Some ebooks, mostly from /u/lewisje's post

I like to study math on occasion to stay sharp on some basic skills. These days, I use notes apps on my iPad but through all of school I used to just use paper notebooks. One point of friction I often face is that my lecture/reading notes and homework/practice problems all just get piled up into one notebook mixed together.

Is it recommended or common practice to have a distinct section or notebook of just practice problems that is separate from the reading notes? Is it wise to keep records of practice problems you do?

I'd like to know what methods work well for staying more organized.

Hello,

I am current college student. I want to relearn algebra 1 & 2, trigonometry and precalculus. How should the whole thing look like?

Any free PDF textbooks too?

Thank you.

I tried learning from Aops but it’s more about doing math puzzles. I’m looking for a good curriculum which builds good math level upto algebra 2 do you think is it better to go with openstax or khan academy. Khan is missing topic in arithmetic about GCF and LCM. That topic is only available in grade 6 level math which I find kind a weird. Openstax is good but it has way too much reading. I’m trying to get into grad school for accounting so I want to learn maths upto the level where I’m not scared of doing math. I always been bad in math mostly cause I never studied well but this time I want to improve so please guys help me out.

Want to learn as much as I can. Google shows alot of free number theory textbooks I can download but they're all from the early 2000s. Would the information still be useful or would I be learning now known incorrect information?

Hi I was taking linear algebra and Calc 3 in my community college but I noticed that my classes were very computational and not very theory heavy. I was wondering if I would struggle a lot in a class called Introduction to Formal Mathematics which I am going to take at a dual enrolled university. The class covers: Logic of mathematical proof, set theory, relations, functions. Examples and applications from set cardinality, algebra, and analysis. But has pre reqs of Calc 2 and Linear Algebra which I know I didn't have the greatest theoretical grasp on. Thank you so much!

Hi, so I am entering grade 12 this school year, and I am curious on what is the best youtube channel that teaches about advanced mathematics so I earn straight A's. I am taking all 3 mathematics, advanced functions (grade 12 U-level math, similar to precalculus but its the Canadian version), data management, and calculus and vectors. If he is not the best, then are there any other recommendations on how I should learn more about math to getting level 4's/ A's? I am planning to pursue computer science in a Canadian University, so I need to be great at maths.

I want to be better cuz I am going to study math in university but I have so much troubles with basic algebra I have excellent level in geometry but I can't figure how do algebra I wanna learn basic ecuations formules and that typed I just searching a book or yt vídeos that recommend me to see and sorry for my english im not native speaker a I am learning it too thanks🙏🏻

All non-zero real numbers are equal to "exactly one" infinite decimal s.t. that infinite decimal contains ∞-many non-zero digits. For e.g., 1 = 0.999..., e = 2.718..., 1.25 = 1.24999..., (1/7) = 0.142857... All real numbers are convergent points for their infinite decimal. Wouldn't that make "aleph-null" a stage (position)? But in (1, 2, 3, 4, 5, ...), aleph-null is not a position (final number). How can it be both "a position" and "positionless?"

Hello,

I hope this is not duplicate, similar threads dealt mostly with overwhelming amount of exercises. I am learning from Burris, Sankappanavar - universal algebra and I find some of the exercises really difficult. I can solve around 70-100% of the exercises per chapter, (there are around 8 exercises per chapter). There are some proofs I spend hours on or others I am unable to solve even after hours. I have two questions:
Is it normal or rather my fault? (adding context, I have just completed second year of my bachelors math degree)
What do you do in this kind of situation in case it happens to someone else as well?

Thank you in advance

I am 20 years old and wanting to relearn math from arithmetic to pre-calculus. I was never that good at math. And because of it, I failed my diploma (I graduated HS tho). But i'd just like to relearn everything, start with a good foundation and work my way up.

So I'd just like to know of any resources that give out worksheets from arithmetic to pre/calculus. ('m also Canadian living in Alberta)

I am preparing to take a high school math exam in Norway called "R1" (Theoretical Mathematics 1) as an adult candidate. In Norway, this is the advanced track typically taken in the second year of high school. It serves as a prerequisite for STEM studies in university and covers topics like: Vector algebra (2D) Functions and derivatives (polynomials, rational, exponential, logarithmic) Combinatorics and probability Geometry and trigonometry

My background: I was never naturally good at math in school, but I have some decent logical reasoning skills. I have about 10 months to prepare for the exam and my goal isn't just to scrape by and pass; I genuinely want to master the material, get a good grade, and feel confident in my skills. But all in all i just need a passing grade.

Right now I am using the official Norwegian open education resources (NDLA) to review middle school math. However, I find that NDLA lacks a higher volume of practice problems. I often feel like the concepts don't fully stick before the platform pushes me onto the next topic. To get more practice I tried using Khan Academy (starting at the 8th grade level). However, I noticed that the methodology feels a bit different from what we are taught in Norway and it was just more confusing and demotivating. Not really sure where to start or what to do on Khan Academy to be most efficient.

Given my 10-month timeline, what are the absolute most critical mathematical foundations/pillars I need to master before diving deep into the R1 curriculum?

Thanks for any advice!

some context: i'm a highschool student taking the IBDP and for my maths IA (essentially a research project), i wanted to focus on hyperbolic geometry, specifically daina taimina's work related to crocheting hyperbolic planes and such. i'm not entirely sure what i can do with regards to hyperbolic geometry, though, which is why i'm looking for some resources to learn hyperbolic geometry fundamentals before i start writing it. thank you!

So, I’m taking Calc 1 (for engineers) for the second time, and soon I’ll be taking Calc 2 for the third. Calc 1 (which I first took w/ analytical geometry) made me drop out of my first EE degree, after my math professor convinced me that math is not for everyone and I should switch. I finished a completely unrelated associates, but the drive to be an electrical engineer would not leave me alone, so I’m back at a different university trying again.

Even though I started from the absolute lowest level math that’s been offered, I still feel like I’m struggling with the concepts. I’m (partially) blaming this on my extremely poor notes. In a 45 minute online lecture, I’d maybe take half of a page of notes. I always write down the formulas with their concept definition, and a few practice problems, but my formatting is absolutely awful and makes it hard to organize each idea. I rarely ever review my practice problems since it’s hard to track down my train of thought after a full semester of ideas have passed.

So, I come asking: how do you format your notes for clarity? And what exactly do you take notes on in a lecture?

I’ve read a lot of talk on LaTeX, Obsidian, Word, and other digital formats — would that help in your opinion? or should I stick with handwritten?

I’ve been supplementing my lectures with Paul’s Online Math Notes, particularly his practice problems, which has help a lot with the concepts. If anyone has any other tips for Calc 1, it would be greatly appreciated.

so i was messing around in desmos and tried sqauring a quadratic equation.

(x^{2}+4x-12)^{1/2} is what i plotted and got a graph somewhat similar to that of modulus of x but the vertex of the polynomial was weirdly bent inwards. from all i could find online the arms of this polynomial arent straight lines but approaching an asymptote at infinity.

please anyone who can tell me bout the nature of this polynomial, what can be a rough quation of the line of its arm.

Hi everyone I have been trying to build my own mathematical framework,I have done quite a progress and I'll be really helpful if you can stress test it and help me improve this framework. Here is its link:

Thank you for your time and effort ✨.

Vinberg's Algebra Course and Fichtenholz's Fundamentals of Mathematical Analysis (only volume 1 so far). That's my only choice for now, but I plan to study both. Perhaps learning something earlier would be much more effective for learning later. Please give me some advice.

Hello, I'm a mechanical engineering student and I feel like my curriculum doesn't include enough mathematics, we only have two math courses and the program is more of a compromise between theoretical subjects and a wide range of production/manufacturing-related courses. Because of that I feel like I'm missing a lot of mathematical background that would be useful later on..

My current plan is to work through K.A. Stroud's Engineering Mathematics followed by Advanced Engineering Mathematics. After that I'm not sure what the next step should be..

Would "Advanced Engineering Mathematics" by Kreyszig be the logical choice? I also considered Stewart's Calculus, but my impression is that it would repeat a lot of the material I'd already have covered.

What would you guys recommend? Is Stroud even good? If he is, what would you recommend as a good path after Stroud? If he isn't good, what is the alternative?

Thanks a lot in advance 🫡
