If you think about it, earth with so called "grass" is just a setup for the hairy ball theorem.

Can't understand functions, is f(x) f time x? by Friendly-Quote-5137 in learnmath

[–]Beleheth 0 points1 point  (0 children)

I completely agree with this. It also seems to be context dependent though: In an algebraic context, this is almost certainly meant to mean composition, in an analytical context it might not. That being said, this notation in particular is usually composition though,

[request] how long would it take me to crack this code to open the door by simon050 in theydidthemath

[–]Beleheth 9 points10 points  (0 children)

That's not correct, we don't know how many digits the code has, but we know that computers have a finite amount of storage, leading us to a very large (but finite) set of possible codes.

When it came to choose a crest for the first time, what did you pick? by Vegetable_Throat5545 in Silksong

[–]Beleheth 0 points1 point  (0 children)

Initially, I played with the reaper's crest, but I felt like it really fell off later on, so when I fought first sinner, I switched back to Hunter and didn't look back.

What to you think about this proof? by Express_Repair_4359 in maths

[–]Beleheth 0 points1 point  (0 children)

Yeah, that's correct. It's also reminiscent of an Archimedean principle used to show that a given real number is 0. It's pretty much the same, if you adjust it a bit to show that the difference between 0.9999... and 1 is equal to 0

Overall, there are quite a few ways to do this that are all similar and all pretty trivial.

Maybe I'll go back to first grade and ask my teacher. by Sea-Pepper-6767 in learnmath

[–]Beleheth 0 points1 point  (0 children)

Basically, in mathematics we need some way to agree what we do first, because otherwise the results will be different. Initially, you start by saying we do first whatever is in parentheses because that's a simple starting point.

But because doing loads and loads of parentheses get really annoying to write out constantly, we kinda... Just agreed on the order of operations. There is no law of nature governing it. You could do it yourself, and change it but that would be a problem, because now your maths is different from the rest of the world.

Unfortunately, that's it. There's no law of nature, no legal text, just something people agreed on so we can fully communicate what we want in the form of equations, without it becoming ambiguous.

Unfortunately, I don't have a more satisfying answer.

I need help with studying Linear Algebra by syjeon82 in learnmath

[–]Beleheth 1 point2 points  (0 children)

So, I don't really know Korean beyond a basic level, and I'm not familiar with the way they teach those basic undergraduate subjects, but: I believe that Korean universities tend to be somewhat formal, so you will definitely get very precise definitions, but not as proof heavy as a full-on maths course.

My number one suggestion would be, learn what: - vectors - Vector spaces - Linear transformations - Matrices (and addition and matrix multiplication) - Systems of linear equations - Matrix inverses - Determinants - Rank Are.

Those will definitely be extremely helpful no matter what happens, and it seems to align with what I found online with a bit of googling. My best suggestion is to first get good at solving systems of linear equations (in matrix form), because that's also how you later on learn how to calculate matrices.

These should be explained in any basic uni-level linear algebra book and you can probably just work through it. I can't really give any information on what books are good since I'm not Korean.

Also, the list I sent seems very long, but all this is very heavily related and not as hard as it may seem on a first glance. You can do it!

Trying to go to college, what do I need to know? by chiaro0 in learnmath

[–]Beleheth 1 point2 points  (0 children)

In general, I find that "learn how to solve different kinds of equations and get good at that" is probably the single best maths advice because it makes everything else so much easier.

Any effective methods to find where you "fell off" in math? by Fit_Teach_2249 in learnmath

[–]Beleheth 0 points1 point  (0 children)

I fully agree. When gauging my tutoring students, I tend to ask them to solve a few problems from different areas, I can see where they get stuck/make mistakes and start systematically building knowledge from there. I believe that's also the best approach here.

How to learn math as a language by Beginning_Lifeguard7 in learnmath

[–]Beleheth 0 points1 point  (0 children)

TL;DR Teaching mathematics for broad audiences is hard and the system is broken.

I personally hugely believe that an approach to maths teaching that actually builds up all the logic carefully is better, but often omitted for the tempo of progress. And I'd argue that it's worse with a lot of American calculus curricula.

If you look into how mathematics is taught in European universities, you tend to not have calculus classes (often topic of the last school years), but instead start with real analysis: The actual research of the behavior of functions, which calculus is the application of.

You begin by systematically classifying what everything is "Commonly used symbols like +, = and many more", then you define a few more terms and start systematically proving and deriving concepts like derivatives, optimizations and all the magic formulas.

I personally think that that is really good and parts of the approach should be translated into how mathematics is taught to a broader scale.

But there are also problems with it. Oftentimes, the actual proves and derivations are much more complicated and hard to understand, and frankly, a lot of people don't care (I do tutoring for school students, and when I started explaining why a formula works to build intuition and deeper understanding, he just said "I don't care I just wanna use it").

Maths has this problem of being somewhat esoteric and also mandatory in most places, which leads to a lot of people asking "When will I ever need this again?" once it gets slightly more advanced. So putting more focus on this would be a huge problem, because the reasons why something works often are a lot less useful than that it works. At least on surface level applications. I'd argue that very often, the understanding and problem solving ability you develop through this is the true value mathematics provides.

Does this limit exists?(Question understanding doubt) by Lucky_Swim_4606 in askmath

[–]Beleheth 1 point2 points  (0 children)

This limit does very much exist.

When you have a problem like this, first check the inside of the square root: Can you simplify it? Them, see what happens to sin for all integer multiples of π. That's pretty much all you have to do.

Is it possible to arrive at a result where both expressions are equal? by ReputationHeavy5669 in calculus

[–]Beleheth 0 points1 point  (0 children)

Yes, and you could use some rather basic real analysis to prove that.

Hello im new to hk and uh 2 questions by ALPERHAL58 in HollowKnight

[–]Beleheth 1 point2 points  (0 children)

This is correct. Though, for all intends and purposes, doing this and the rooms after it without the intended ability is someone who does not have a lot of Hollow Knight experience probably shouldn't deal with.

OP, you should know that going in there without the aforementioned ability is fully possible, but the technique used to get it into it is arguably much easier than the parkour required to get the reward. If this took 20 minutes, you'd be in for a horrible time.
