"Why do I have to learn math when I'm never going to use it in real life?"

Why do you say?

Because you are always going to do shit you don't like no matter what you choose so you need to learn to shut up and do the work. Also, there are really few jobs that don't have or aren't improved by math.

To help you grow up into something more than a complete brainlet. Americans are already among the worst ranked in math among first world nations, you should at least make an effort so people don't confuse you with a third world nation.

That is a horrible suggestion.
>>
>>8960492
This. >>8960499

How is the quotient rule even difficult? If rational functions scare you, just write the denominator raised to -1 and use the product rule (my specialty).

Is this bait?
6/10

I know that, when x approaches 0, sinx=x and tgx=x. But, doing some multivariable limits, I've found that the same is true for arcsinx, arctg, e^x-1 and ln(1+x).

So now I'm wondering, since I probably won't find all of the approximations in the problems I'm doing, if there's a list somewhere with all of these? I cannot seem to find it anywhere, only the small-angle ones, about sin and tg.

Also, what about when x approaches infinity?

>how does a periodic function behave as it tends to infinity
:thinkan:
>>
>>8962930
Just expand them yourself, it's just a Taylor series.
>>
>>8962935
Actually, that part was utterly retarded, ignore that. To be fair tho, I wasn't asking only about the periodic functions, but I guess the other ones would be easy to solve.

>>8962936
I honestly have no idea how to do that, and I'm not sure I have time to learn now. I've got a lot of ground to cover until the 15th, and that would take a bunch of time, and in return I could realize that functions listed here are the only ones.

But if I don't find some useful list, yeah, I might have to resort to learning how to do what you just said.

If someone were to take a couple of hits of DMT and they managed to see Heaven and/or God. Is there a chance that you could actually die just from seeing these visions and knowing that you could be deceased? This is the one thing that scares me about ever trying that drug.

I don't think God would be visiting degenerate hippies and I think that He would be smart enough to realize that you are not in fact dead.

>>8961153
God would visit anyone who believes in him since that is the only way he could be seen. How do you think you see him whenever you die, Anonymous?

You lied to me, /sci/. There isn't any evidence to support our bodies produce DMT or that it gets released when we dream or are dying. What the fuck?

because then they wouldn't be missing, and there would be a new "missing link" according to creationists. there are lots of fossils that show stages of change.

Numberists may claim that two comes after one, but what about the infinitely many number between one and two? Sure there's 2.5, 2.3333, and even 2.838483837473, but what about all the other numbers? Checkmate numberists. Numbers were all created at the same time and have no chronological order.

"Missing link" is an outdated term, same as "transitional form." Paleontologists and evolutionary biologists don't look for a distinct form, but a certain trait.

What math do you actually need to teach at a high-school level?
28 posts and 3 images submitted.
>>
>>8960793

Read one of those dumbed down versions of Euclid's elements

Then read it again to make sure you get it

now you can teach geometry.
>>
>>8960793
You need at least real analysis. Even if you don't teach calculus, you need to understand math as more than just "memorize these things".

Think about the rick and morty episode with the nested microverses. Each succession is less advanced than the previous. That's what happens to us as a society if we imitate rather than understand.
>>
>>8960981
This is true if the student has higher goals for math. My high school wasn't shit tier, so it offered calculus AB and BC, which are analogous to calc I and II, junior and senior year. For AB, my math teacher didn't have a super deep understanding of math, but was a great teacher, so I thought I was learning a lot. I still did fine in the class and on the AP exam. In BC, I didn't really like the teacher at the time, because his lessons weren't as easy to understand. However he taught me how to think about math, and in college I see now why he taught things that way.
However for the average high school student who has no higher math aspirations and will not learn anything past trig, you don't need to know very much.

ITT: Batshit insane (pseudo)science

I just reviewed a thesis. It was stated that memory and consciousness are stored as electron spin states in neuronal microtubules. Also, these tubules alter the geometry of space and time, causing memory and consciousness to be rooted deep in the cosmos.

Sources: some shit-tier open access journals and one low ranking journal from Elsevier.

My uncle had to go to Kaiser three times complaining of severe chest pain radiating into his left arm, shortness of breath, and pale complexion before they would even entertain the idea of putting him on a heart monitor.

If doctors knew anything, they'd all live to be 120 years old. Dead doctors don't lie.

>Dieudonné writes [9]:-

>A general theory of duality for locally convex spaces had to be worked out: Schwartz and I had started its study for Fréchet spaces and their direct limits, but we had met a series of problems we could not solve. We therefore proposed them to Grothendieck, and the result turned out to exceed our most sanguine expectations. In less than a year, he had solved all our problems by very ingenious new constructions; then, with the techniques he had developed, he started to work on many other questions in functional analysis.

So Laurent Schwartz and Jean Dieudonné were brainlets compared to Grothendieck.
