Pretty sure p=1013.

Since 2027 is prime, the multiplicative group of integers modulo 2027 has order 2026, which has prime factorization 2*1013. If such a p exists, this means the cyclic subgroup generated by the element 2024^p must divide 2026, and so p must be either 2 or 1013. We can check that 2 doesn't work: 2024^2 - 2023^2 = 2024+2023 = 4047, which is not a multiple of 2027. Thus if p exists it must be 1013.

Not sure how I'd verify this p by hand but WolframAlpha confirms it.

I dunno if I'm just weird or what but Cal 2 to me was much harder than Cal 3.

That's pretty normal. I've not watched the posted video but IMO one thing that makes Cal 2 much more difficult for students is that you've got to choose between different techniques (either convergence tests or integration methods). In calculus 1 and earlier classes you usually don't have such decisions (optimization in calc 1 an exception here).

This just reminds me of how much I struggled with gfology. Maybe I should take a look at it again.

I liked that book. Wilf has a good sense of humor. The footnote for the "x(d/dx)log operation" is something like "the best motivation for the above program is the fact that it works"

I Iderivedx do you also have a PhD?

yeah

My favorite part about combinatorics/graph theory is that there are a lot of proofs that boil down to random magic tricks. Obviously that can lead to its own frustration but in some ways it was more of a style than a specific discipline compared to e.g. my friends who did commutative algebra.

What was your research in?

I remember one graph theory proof in class used Cauchy-Schwarz out of seemingly nowhere. Although, I think graph theory has some of the neatest tricks/ideas. The discharge method is my favorite thing to tell people who have enough math experience to get the gist.

I do enumerative combinatorics.

Not to hijack your topic but the only math I did in HS was intermediate and then geometry. Now I'm signed up for college and my counselor assigned me a pre-calc class. How can I prepare for something like that? I haven't done math for years. I need the class for my major which is computer science.

Paul's online math notes (focus on algebra section) for something written with practice problems: https://tutorial.math.lamar.edu/Classes/Alg/Alg.aspx

For lecture-style things, probably Khan Academy or Organic Chemistry Tutor on youtube.

Start working through topics and when you run into concepts you don't remember, identify them and go refresh, then continue.

Graph theory and then also semigroup things (I had a weird advising situation).

Graph theory is tough. I could never really pick up the intuition for the proofs. One of my committee members was a graph theorist and he decided to tell me there's a better way to do a proof during my defense.

Anteaterking posted...

Yeah, PhD

Oh nice. What research area?

Anteaterking posted...

I think part of the issue is that it's really easy to read upper level mathematics and convince yourself you understand it if you never actually put it to the test.

IIRC you've got a math degree?

RetuenOfDevsman posted...

I think it'll be important to actually do the homework questions.

You can't really learn math without working problems. Reading results only gives you a general idea what's going on.

The liberals that fantasize about putting leftists or non-voters in camps if Biden loses are probably not liberals and just haven't admitted it to themselves yet.

It's only been a few hours. Wait for the students to get too annoying and then the cops will be happy to beat them up.

Dems doing an excellent job being the handmaidens of fascism.

You should probably work though a book that introduces mathematical proofs. I think a new one that I have heard good things about is "The Tools of Mathematical Reasoning" by Lakins. It's expensive but I'm sure pdfs exist.

Another one that's actually open source is "Book of Proof" by Hammack: https://www.people.vcu.edu/~rhammack/BookOfProof/

Proofs in high school geometry are only somewhat representative of proofs you get in the rest of mathematics. However, there are not many more topics you can learn without having to know how to prove things.

If that's what you believe.

I asked you what you'd do if Trump won and you said you'd vote! I don't have to just believe it: you said it yourself. Also I've not lectured at all on morals! You're projecting.

So is there something you'd like to tell us?

Not Trump. lmao God what a nightmare

Yeah the only one of two candidates that could be talked out of genocide is apparently a bad choice.

Lol

Hey man how's that been going so far?

I think a lot of liberals would be well served if they stopped weighing "things that might happen at some point in the future" equally with "things that are currently happening."

Cemith posted...

My plan is to vote against the aspiring fascist, for the guy that I believe could eventually see reason. Pretty sound plan.

So you'll do nothing in the event you pick the loser except act smug about it. Neat!

Cemith posted...

Cool! So you're voting for the guy we can talk down and not the guy that would eat genocide for breakfast, right? And not RFK, the conservative in a mask, who has no chance of winning the election, right?

I am not voting for RFK. Also, liberals who are arguing for a pro-genocide candidate don't get to use the threat of a genocide to pretend to be the adults in the room.

What things?

Provide material or monetary assistance, protest, strike, etc. Depends on what is happening and what it needed.

Cemith posted...

Okay. So when you don't vote, and Trump does genocide but also helps oppress domestic minorities, what's your plan then?

Do things to mitigate impact or make such actions more difficult/costly. Who said I wasn't going to vote? Also, what's your plan?

ssb_yunglink2 posted...

Because you want to feel good about yourself, no?

I have been over this:

lderivedx posted...

Nope.

Cemith posted...

Do you have a more compelling reason to abstain?

Yeah I already said it: I'm not voting for someone who is assisting a genocide.

Cemith posted...

Okay! So now you're abstaining for what is effectively no reason.

How truly brave of you.

The only reason to abstain is to feel good about myself???

Cemith posted...

Cool! So when Trump wins and does genocide anyway but more. Will you feel pretty good about yourself?

Nope.

I will not vote for someone assisting in a genocide.

This is actually the scummy secret behind insurance that has made healthcare as expensive as it is. They generally don't pay. They send you an explanation of benefits letter each time you use your insurance that shows what the company actually did, and only rarely have I seen them pay anything.

Generally all they do is make the provider (eg, doctor/hospital) accept like a tenth of what they bill because the whole health insurance industry is a cesspit of cockroaches, which in turn is why the providers have to bill so damn much.

It feels like a protection racket. I don't know if the dentist was giving me the "normal" price and marking up uninsured people's bills or if the insurance company said "look if you don't cut costs for our clients we won't work with you when we do decide to cover costs," and so the dentist had to do some stuff at a loss.

One thing that really annoyed me about my old dental insurance was that it lowered prices even when the insurance refused to pay.

It's fine. I think Korra is a better protagonist than Aang, but the writers' attempt to address political topics while knowing nothing about politics is a bit annoying. For example, the antagonist intending to represent fascism is treated the most sympathetically, despite having slave labor camps and (hinting at? I can't remember if it was hinted or explicit) executing dissidents. Also the lack of imagination regarding how society would progress (people have magic abilities but society and technology progresses in the manner that early 1900s liberal democracies did) was a bit disappointing.

butterfly catching isn't too bad outside of a few janky camera angles. i think the ultimania guide has a path in its maps that's pretty useful
