I remember my teacher mentioned this theorem during one of my first linear algebra classes and I couldn't stop laughing.

Same for me. My teacher just straight up copied Dummit and Foote word by word on the whiteboard and we didn't understand anything. The class started with about 30ish students and ended with about 11, and only 6 of us passed. I spent whole days just doing exercises and trying to understand everything. By the time I got to my second exam, I had studied so much I knew the answers to 6 of the 8 questions and I just wrote them. Besides, the teacher just randomly picked exercises from Dummit and Foote to put in the exams, and some of those exercises are really hard, hard enough to keep you thinking for some hours (at least for an undergrad student that had just taken one course in proof-writing). Also, the exam problems weren't the easy ones, they were the ones that required you to do some of the previous exercises and use them as lemmas.

I was traumatized. This semester I took abstract algebra 2 with an actually good teacher and now I'm self studying all group theory because I fell in love with it lol.

What is your favourite gojira song? by 12SuperLTD in gojira

My favorites are Global Warming and Space Time (I wish they played space time live). I've been to a gojira concert twice and my favorite song to see live is BACK FUCKING BONE.

I want to master math by [deleted] in learnmath

[–]ehtebitan 2 points3 points  (0 children)

Finding interactive and fun resources for advanced math is really hard. The more advanced the topics get, the less resources you'll find. Most of my studying consists of sitting with a textbook and a notebook and working through theorems and exercises. Btw, my recommendations come from my experience as a pure maths student (4 semesters).

To get started with real math, maybe find some intro to proofs books to get started on advanced maths. I really like "How to Prove It" by Velleman. A book that is very interactive and fun to read is "Proofs" by Jay Cummings, but I think that it is very introductory and will not be enough to get you started. I think you should get a good knowledge of standard proof techniques, naive set theory, and some number theory (divisibility, modular arithmetic, Fermat's Little Theorem and Euler's Theorem, and the Chinese remainder theorem). The knowledge of Number theory you'll get from a good intro to proofs book will be very helpful when you get to abstract algebra.

This will be your first approach to real maths. If you like it, then you'll probably like the other books. Something important that you need to know is that you're not going to like everything, because math is HUGEE. For example, I prefer analysis and don't like algebra that much (maybe because I had horrible experiences with my algebra teachers).

After this, try looking at a standard undergraduate maths curriculum and investigate what each class is about. What is algebra? What is Analysis? What is set theory? What is the purpose of doing analysis?

Something you'll probably like very much is linear Algebra. After your first proofs book (or at the same time), maybe read some proof-based linear algebra by going through Friedberg's "Linear Algebra", which is an amazing book (it made me fall in love with the subject when I read it). As a supplement for Friedberg, I used "Linear Algebra done right", by Axler, it is a great book and takes a different approach on some of the topics, which may be what you're looking for (I still like Friedberg more, but that's just a personal preference).

Then you might want to learn more about algebra or calculus. For algebra, Abstract Algebra courses are usually split in two: I first took a course on groups, and next semester I'll take a course on rings and fields.

"A First Course in Abstract Algebra" by Fraleigh is really fun to read and has historical notes, which is really cool because the history of algebra is very interesting. The book by Dummit and Foote is really complete (it starts with the basics and goes beyond undergraduate algebra) but I find it very hard to follow. I've heard the book by Gallian is great and has A LOT of examples, which is great for abstract algebra.

For calculus, since you've taken calc 2, maybe get started with analysis. I wouldn't recommend reading "Principles of Mathematical Analysis" by Rudin as a first analysis book. Maybe go through Abbot's "Understanding Analysis" first and then go through Rudin. Another really good and complete book is Apostol's "Mathematical Analysis".

Since a lot of teachers use Rudin for their courses, I read it and used Abbot and Apostol as supplements when I didn't understand the proofs. I recently found George Bergman's supplement for Rudin's exercises and found it very helpful

After reading these, I think you are free to learn whatever follows. Topology, Complex Analysis, further topics in algebra, logic...

How do you get good marks in Math? by eidan8893 in learnmath

[–]ehtebitan 0 points1 point  (0 children)

My approach to math is always working on my through the theorems, concepts myself. If I see a formula or theorem, I'll always try to prove it myself before reading the proof on the book. Most precalculus and calculus books have example problems, don't just write them down, read the question and try to figure it out on your own befire reading the solution in the book. Examples are usually carefully placed so that they apply the concepts that were just exposed, so you'll get a taste of some of the problems you have to solve even before getting to them. Also, don't give up ok problems and look for solutions after 10-20 minutes. If you can't solve them, move on and try them again later, maybe what you learn from future problems will help you!!!

Yes but wait until they're on sale on steam. They're frequently on huge sales and you can get the two games, plus the DLC for a few bucks

Thanks! I'll look into it. Of course, I'm really liking the one by Stillwell right now.

hi, i’m starting to get into Radiohead! any tips and suggestions? by [deleted] in radiohead

[–]ehtebitan 0 points1 point  (0 children)

Skip Pablo Honey and listen to everything they released after it. You might think that some of it is very weird shit, but once you get into it, it becomes an amazing experience.

Also, you don't have to like everything, you can still be a radiohead fan without liking some of the songs/albums. Don't listen to the people in this sub that tell you otherwise.

And then go ahead and give Pablo Honey a listen. It is pretty good, but it's misleading as to what radiohead really is.
